NGB Form 3621 is the Air National Guard Eligibility Checklist for Enlistment, Reenlistment, or Extension of Enlistment. You fill it out any time you join the Air National Guard, reenlist, or extend a current enlistment, and your packet cannot move forward without it.1National Guard Bureau. Air National Guard Instruction 36-2002 – Enlistment and Reenlistment in the Air National Guard and as a Reserve of the Air Force The checklist screens for disqualifying factors before a recruiter or unit personnel office spends time processing the action, and a “yes” to certain questions triggers additional documentation or a waiver review rather than an automatic denial.
When the Form Is Required
The prescribing directive, ANGI 36-2002, makes the checklist mandatory for every enlistment, reenlistment, and extension in the Air National Guard.1National Guard Bureau. Air National Guard Instruction 36-2002 – Enlistment and Reenlistment in the Air National Guard and as a Reserve of the Air Force Providing the information is technically voluntary, but if you decline to answer, you are disqualified from the action you are trying to complete.2National Guard Bureau Publications and Forms Library.

Where to Get a Current Copy
A blank form is available from the National Guard Bureau Publications and Forms Library at ngbpmc.ng.mil.3National Guard Bureau Publications and Forms Library. NGB Forms In most cases your recruiter or unit Force Support Squadron will hand you a copy inside the enlistment or reenlistment packet. If you download it yourself, check the version date on the form itself; older copies saved to unit shared drives can be out of date.
Filling Out Each Section
The form has five sections. Read the section headers before answering, because Sections II and III are mutually exclusive.
Section I: All Applicants
Everyone answers Section I, whether this is a first enlistment or a reenlistment. The questions cover:2National Guard Bureau Publications and Forms Library. NGB Form 3621, ANG Eligibility Checklist for Enlistment, Reenlistment, or Extension of Enlistment
- Conscientious objector status, past or intended.
- Sole surviving child status.
- Citizenship and supporting documentation.
- Current or past ROTC enrollment.
- Participation in organizations or activities considered subversive under federal law.
- Any ongoing investigation by a law enforcement or military agency.
- Alcoholism, rehabilitation, and drug testing history.
- Mental health treatment or diagnoses that could affect duty performance.
- Pending civilian or military charges, court-martial history, and convictions.
- Prior service in any branch or component.
- Peace Corps service.
- Tattoos, brands, and other body modifications that may conflict with ANG appearance standards.
Most items call for a simple yes or no. Answer honestly. Responses are cross-checked against Department of Defense databases and law enforcement records, and a false statement can lead to criminal penalties and separation.
Section II: Enlistment Only
First-time enlistees answer an added set of questions about any legal or military charges that came up between the initial application and the enlistment date itself. Skip this section if you are reenlisting or extending.
Section III: Reenlistment or Extension Only
Reenlistees and those extending answer questions about any legal or military charges that arose during the current term of service. First-time enlistees skip it. The split exists because reenlistees already have a service record that will be reviewed alongside their answers.
Section IV: Comments
Every “yes” answer from the earlier sections needs an explanation here. Be specific: for a legal charge, include the date, jurisdiction, charge, and outcome. Vague notes only send the form back to you for detail and slow down processing.
Section V: Recertification
Section V is where you sign and date the form, certifying that your answers are true and current. You also acknowledge that you must recertify at the actual time of the enlistment, reenlistment, or extension ceremony. If anything changes between the two signatures, report it to your Force Support Squadron before you recertify.2National Guard Bureau Publications and Forms Library.

What a “Yes” Answer Actually Means
A “yes” does not disqualify you on its own. It triggers a review. Your recruiter or the unit’s Force Support Squadron reads your Section IV explanation and decides whether the issue needs a waiver, additional documentation, or a look from the state’s Joint Force Headquarters legal office. A minor traffic fine is usually straightforward. Pending felony charges or a documented history of substance abuse treatment can require command-level waiver approval and take weeks to resolve.
Do not try to answer “no” to skip the scrutiny. If the discrepancy shows up later in a records check, you can be separated under fraudulent enlistment provisions, which is far worse than the original issue in almost every case. When in doubt, disclose.
Turning the Form In
Hand the completed form to your recruiter for an initial enlistment, or to your unit’s Force Support Squadron for a reenlistment or extension. It becomes part of the packet and is reviewed alongside your DD Form 4 (Enlistment/Reenlistment Agreement), medical screening documents, and any waiver requests tied to your answers.
Your responses are protected under the Privacy Act of 1974 and are not shared outside the personnel and legal channels needed to process the action.1National Guard Bureau. Air National Guard Instruction 36-2002 – Enlistment and Reenlistment in the Air National Guard and as a Reserve of the Air Force Once your enlistment or reenlistment is complete, the signed form is filed in your official military personnel record.
Mistakes That Delay Processing
Most problems with this form are simple. Filling in Section II when you should be in Section III, or the reverse, sends the packet back for correction. Leaving the comments section blank after a “yes” answer guarantees a delay. Forgetting to recertify on the day of the ceremony leaves the packet incomplete and can push your enlistment date.
If weeks or months pass between your first signature and the recertification, reread your answers before you sign again. A new traffic ticket, a change in medical status, or a new tattoo can all require an updated response and explanation. Catching the change yourself is far cleaner than having it surface during a records review after the fact.
