How Many Checks or G-1450 Forms Should Be Submitted With a B1/B2 Extension Application?

2 min readAdapted by TOP EASIER

For different combinations of Form I-539 and Form I-539a, this article explains how to separate checks or G-1450 forms when filing a B1/B2 extension, aiming to reduce errors by Lockbox staff and the risk that an entire application is returned, with fee-splitting examples for multi-person filings.

Many people applying for a B1/B2 extension often wonder whether to use separate checks or multiple G-1450 forms, or just one check. This is easy to understand, as the goal is to speed up application processing and reduce the chance of errors by busy LockBox Facilities staff.

Only One I-539 Form

If only one person applies for an extension, the fees required are a $370 application fee plus an $85 biometric fee. In this case, it doesn't matter whether you fill out one check or separate two checks, because there is only one applicant. The same applies to using G-1450 forms: one or two forms are both acceptable.

One I-539 Plus One or More I-539a Forms

In this situation, writing one check is theoretically fine, but to avoid confusion for staff, it is recommended to separate checks. For example, for one principal applicant plus two dependents, you can write 4 checks in the amounts of: $370, $85, $85, $85.

Two I-539 Forms and/or I-539a Forms

In this case, it is even more advisable to separate checks and arrange them in the order of one fee corresponding to one application form. This way, if one application form is filled out incorrectly, at most that form will be returned, without affecting the other application form.

For example, this reader's situation involves a couple, a child, and the wife's parents—five people in total applying for a B2 extension. They need to fill out two I-539 forms, one with two I-539a forms attached and the other with one I-539a form attached. The total fee is $370 x 2 + $85 x 5, so it is recommended to write seven separate checks. If you don't want to write too many checks, at least separate them into two: one for $625 ($370 + $85 x 3) and one for $540 ($370 + $85 x 2).
