What are the physical and mailing addresses on Form I-90? How are they different?

In the Information About You part on your Form I-90 (Part 1), you have to provide your mailing and/or physical address. Mailing and physical addresses are almost always the same because people generally prefer to get their mail where they actually live. You should provide both mailing and physical addresses only if you prefer to receive your mails to a different address than where you live.

Note that you must provide an address that is in the United States because U.S. Citizenship and Immigration Services will not send your green card outside the U.S. territory.
