Hello - I need to bring my mother to Social Security Office in Rockville to submit documents requested in connection with her application for benefits claim and wanted to find out whether a prior appointment is required or just walk-in is fine.

They also have a drop box inside for documents. Limited amount of people allowed inside the building because of Covid practices. 10 minutes Maxum for inside appointments once you are given a number. You may want to request an appointment at some point. Requested appointments allow for more time.

You can walk in and it has no wait time very early morning.

Hello, having an appointment will make your appointments faster however, they do take walk ins but from my experience, make sure you are there 30min at minimum before they open because the line starts to get really long
