ITA Intro

Invitational Travel

An invitational travel authorization (ITA) may be used to reimburse certain travel and transportation expenses of an individual who is not a Service member or civilian employee. ITAs must be issued judiciously to ensure prudent, proper and ethical use of appropriated funds. A sample ITA is posted on the DTMO website.


An invitational travel authorization (ITA) may be used to authorize travel for an individual who is not employed by the Government, is a volunteer covered by 10 USC §1588, or is intermittently employed by the Government under 5 USC §5703.  An individual intermittently employed by the Government under 5 USC §5703 serves as an expert and consultant and must be appointed under an appropriate authority.  Experts and consultants must be appointed by the Secretary of Defense or the Secretary of the Navy IAW DCMO Administrative Instruction 2, "Employment of Experts and Consultants" dated April 20, 2017.  Appointments are approved via DD Form 2292.


According to the Joint Travel Regulations (JTR) para. 030501, an authorizing official may issue any of the following individuals an ITA under 5 U.S.C. § 5703 if all of the applicable requirements and limitations are met. Authorizing Officials in Table 3-2.1 are responsible for ensuring that their organization’s ITA travelers meet the requirements of 5 U.S.C. § 5703 and are “legitimately performing a direct service for the Government” (Use of Appropriations to Pay Travel Expenses of International Trade Administration Fellows, 28 Op. O.L.C. 269, 275 (2004)).


1. An employee serving intermittently in the Government service as an expert or consultant and paid on a daily when-actually-employed basis, or serving without pay or at $1 a year, may be allowed travel and transportation allowances while away from his or her home or regular place of business and at the place of employment or service (5 U.S.C. § 5703 and 41 C.F.R. § 301-1.2). Only a consultant or expert who is employed for 130 days or less of full-time Government service, performed in any continuous 365-day period is eligible. When Government service is not intermittent, no authority exists for per diem or AEA at the regular PDS (35 Comp. Gen. 90 (1955) and 36 Comp. Gen. 351 (1956)). However, per diem may be authorized in connection with another TDY at a place of duty away from the regular duty location.

2. A college or university faculty member requested to perform travel for consultation on the recruitment of college students to Government service (37 Comp. Gen. 349 (1957)).

3. An individual called as a witness in adverse administrative proceedings whether on behalf of the Government or of a Service member or civilian employee (48 Comp. Gen. 644 (1969)).

4. An individual requested to participate in a pre-employment interview (57 Comp. Gen. 192 (1977)). See JTR, Sec. 0306.

5. An escort or attendant who is not a Service member or civilian employee (59 Comp. Gen. 675 (1980), B-189010, August 15, 1977, B-187492, May 26, 1977, and B-186598, May 26, 1977).

6. A dependent attending anti-terrorism, political unrest or security training or briefing in preparation for a PCS to a foreign OCONUS location (71 Comp. Gen. 6 (1991) and 71 Comp. Gen. 9 (1991)).

7. A guest speaker at an event held by a Service or agency in service of training efforts (60 Comp. Gen. 303 (1981)).

8. A volunteer covered by 10 U.S.C. § 1588. See DoDI 1100.21 and DoDD 5124.02 for more information about statutory volunteers donating their services under 10 U.S.C. § 1588. An Authorizing Official in Table 3-2.1 must certify that the travel meets the requirements of 5 U.S.C. § 5703 and the volunteer is “legitimately performing a direct service for the Government” (Use of Appropriations to Pay Travel Expenses of International Trade Administration Fellows, 28 Op. O.L.C. 269, 275 (2004)).

9. An individual serving without compensation on a Board of Visitors as specified in DoDD 4515.12 and statute (10 U.S.C. § 7455, 10 U.S.C. § 8468, 10 U.S.C. § 9455).

10. A witness before a military court martial or preliminary hearing conducted under Article 32, Uniform Code of Military Justice (10 U.S.C. § 832). See JTR, par. 030702.

11. An individual who serves as an organ donor for a Service member when authorized under Service regulations. See JTR, par. 033009.

12. For any other individual, including a spouse, travel must be pre-approved by an Authorizing Official in Table 3-2.1 and meet the requirements of 5 U.S.C. § 5703 and be “legitimately performing a direct service for the Government” (28 Op. O.L.C. 269, 275 (2004) citing Memorandum for Michael E. Shaheen, Jr., Counsel, Office of Professional Responsibility, from Robert B. Shanks, Deputy Assistant Attorney General, Office of Legal Counsel, Re: Use of Department of Justice Vehicles by Attorney General’s Spouse (Jan. 23, 1984)).


Standard Operating Procedure for Submitting Invitational Travel Authorizations (ITA) for the Defense Travel System

Reference: (a) NAVPGSCOLINST 4650.4J
                    (b) JTR, Appendix E

Enclosures: (1) ITA EFT Information Sheet
                      (2) Travel Request Worksheet
                      (3) DD Form 1351-2 Instructions
                      (4) DD Form 1351-2, Travel Voucher or Subvoucher

1 Introduction

A. This SOP is implemented by paragraph VII 2. of enclosure (1) of reference (a).

B. Individuals traveling under Invitational Travel Authorizations (ITA) are required to use the Defense Travel System (DTS) to file an authorization and submit a voucher for their trips. ITAs are for authorized travel of individual(s) who are civilians, not employed by the federal government, and who are invited to travel to or on behalf of NPS. Note that in accordance with Part I.A.2.c. of reference (b), an ITA “is not authorized for an individual merely to attend a meeting or conference, even if hosted by a DOD component on a matter related to the component's official business.”

C. All ITAs at NPS will be processed by the Travel Office.

D. Travel allowances and travel modes authorized for such persons are the same as those normally authorized for government employees in connection with TDY. This SOP will address how those regulations affect travel within DTS, but is by no means comprehensive. The full regulations governing ITAs are contained in reference (b).

E. Contractors.

1. NPS Contractors. If contracted to NPS in ANY capacity, contractors are NOT eligible to travel on ITAs. Contractors must charge expenses for traveling on behalf of the government to the Other Direct Cost (ODC) line of the contract. If no ODC line exists, or there are insufficient funds on the ODC line, then a modification must be done prior to execution of the travel.

2. Other Government Contractors. If contracted to the federal government outside of NPS, then the following conditions must be met to travel by NPS ITA.

a. Travel is by invitation and for the benefit of NPS.
b. NPS invitation is for the individual as a subject matter expert, speaker, etc.

c. Travel for NPS is outside the scope of the government contract for which they are performing work.

d. Travel for NPS is as a civilian, not employed by the federal government or in the capacity of a contractor.

F. Any temporary duty, including ITAs, of more than 180 days must be approved by the Secretary of the Navy.

2 ITA Forms

A. The NPS organization which is initiating the ITA identifies a need for travel to be performed by someone outside the federal government, and the traveler accepts the invitation to travel on behalf of DoD.

B. The Inviting Official (the person initiating the invitation) notifies the traveler to fill out and fax the ITA EFT Information Sheet (enclosure (1)) to him/her.

1. This ITA Electronic Funds Transfer form contains the traveler’s bank account information. DTS can only make payments in US dollars, and can only make EFT payments to US bank accounts. If a foreign national, or any other traveler, does not hold a US bank account, a paper check in US dollars will be sent to the mailing address provided by the department. The sponsoring department should receive the reimbursement check and forward to the traveler using priority mail.

2. The EFT form also includes a space to enter the traveler’s personal credit card number, which is required for making hotel reservations. If no credit card number is furnished, then the traveler will be responsible for lodging reservations. The cost of such lodging may not exceed the government per diem rate for lodging for the applicable location.

C. The Inviting Official then fills out the Travel Request Worksheet (enclosure (2)), ensuring that every field is completed with as much detail as possible, obtains signatures in the Sponsoring Department section on the back of the worksheet, gets approval of the Security Manager for foreign national travelers visiting the NPS campus, and submits the forms to the Travel Office by either fax (831 656-7632) or secure guard mail. The Travel Office will get the traveler to sign this form later in the process.

1. For travelers entering a foreign country, a country clearance is required. The Inviting Official should contact the NPS Passport Agent at 831 656-2247 or via the Travel Inbox at for further guidance.
2. This worksheet contains travel information that is relevant only to the mission and will not take personal leave into consideration. The Travel Office is only allowed to provide travel arrangements that include roundtrip airfare between their residence or place of business and their TDY location. Any arrangements that extend beyond the scope of the TDY will be the traveler’s responsibility.

D. The Travel Request Worksheet and the ITA EFT Information Sheet contain the information required to complete the traveler’s profile as well as the invitational travel authorization in DTS. Incomplete documents will be returned to the Inviting Official for correction/completion.

3 Travel Authorization

A. The Travel Assistant (TA) in the NPS Travel Office will (1) obtain the determination that the trip is mission essential from the President of NPS; if the trip is mission essential, the Travel Office will (2) construct the traveler’s profile in DTS and begin creating travel for the ITA based on the information provided on the Travel Request Worksheet. The TA will gather information, including the cost of the government airfare for the TDY, maximum reimbursement for lodging, government rate for a rental car (if authorized), including GARS fee, and expected reimbursement for Meals & Incidental Expenses, and provide these to the traveler. Both the Travel Request Worksheet and instructions (enclosure (3)) for completing the Travel Voucher will be sent to the traveler, and, once the traveler returns the signed Worksheet, the TA will then coordinate directly with the traveler to arrange said travel.

B. Travelers need to be informed:

1. That the Travel Assistant in the NPS Travel Office will reserve government flights, lodging and, if authorized, a rental car. The Method of Reimbursement (for airfare only) will default to NPS’ Centrally-Billed Account (CBA), since the invitational traveler does not possess a government travel credit card (GTCC.) ITA travelers are not permitted to use excursion fares nor be reimbursed for purchasing their own airline tickets.

2. That U.S. carriers must be used for all commercial foreign air transportation if service provided by those carriers is available; otherwise reimbursement for the cost of transportation is not allowed.

3. That they will need to acknowledge their acceptance of these terms by signing the reverse of the Travel Request Worksheet.

C. A rental car for an invitational traveler should normally not be required: however, if the Authorizing Official specifically authorizes it, the Travel Office will make arrangements through the CTO in DTS at the government rate.

D. Lodging reservations not to exceed the allowed per diem rates will be made in DTS in accordance with the traveler’s wishes.

E. Travelers should be notified of the TDY location per diem rates (i.e., which define their reimbursement limit) and limitations on amounts for other expense categories for their travel.

F. The Method of Reimbursement for all expenses and reservations, other than airline tickets purchased through DTS on the CBA, will default to PERSONAL.

G. Upon approval of the ITA by the AO, the Travel Assistant in the Travel Office will furnish the traveler with a copy of the ITA printed from DTS.


4 Voucher

A. Upon completion of travel, the traveler will complete and provide a signed Travel Voucher, DD Form 1351-2 (enclosure (4)) for his/her travel, as well as provide all lodging receipts regardless of amount, and other receipts of $75.00 or more. The traveler will then submit these to the Travel Office by fax (831 656-7632) or secure email. Vouchers must be submitted in a timely manner since CBA charges are paid independently of voucher submission. Vouchers are required to be submitted within five working days after completion of travel. Instructions on how to complete the DD 1351-2 are included as enclosure (3).


5 Access to Government Quarters

A. If an invitee only requires access to government quarters, the Inviting Official will request “Guest of the Armed Forces” status from the CO, Naval Support Activity Monterey. Once authorized, NSAM will forward the letter to the travel office so that it may be furnished to the traveler.
