AOS Procedure Part 2

Lockbox Address

Lockboxes are private companies contracted by USCIS to receive Petitions, Applications, accept payments, and create files.

The Lockbox Address differs whether you mail by USPS or use a courier service. Make sure to use the correct address.
Mail your Application ‘package’ registered with return receipt.

If family members immigrate with you their separate AOS ‘packages’ must be mailed together with yours in one envelope. Write on the envelope ‘Original Submission(s)’ followed by the Form Numbers of the forms that are included.

Go to for the current Lockbox Address. Search Direct Filing I-485. Look in the column for your category: Diversity Lottery Winner.
