... in response to I-129F question, posted by surfscum on Apr 24, 2004Yes, you can use a P.O. Box if necessary. Whatever you put in the address block of the Form I-129F, section A.2., will be entered exactly into the USCIS computer as your mailing address for all official mailings. You will still need to provide a residence address for block 15 and also on the G-325A.
Make sure that your P.O. box and residence address are in the same state so there won’t be any question about Service Center jurisdiction.
If you will be moving soon, you may want to wait and use the new address if you aren’t in a hurry.
