Hey Randy thank you so much for your time, I really appreciate. Now, I understand the petitioner should filed the AR 11 no my brother who is an immigrant visa holder . If you allow me to clarify it - The petitioner's address is ok, he lives there and well in another state but it works. My brother listed my address (another state I'm not the petitioner).in his DS 260 that is the one that was wrote incompleted. However, my brother created the MyUSCIS account as many of you suggested. Now in this account, he could see in the U.S Mailing address they have on record, it's not the one that my brother wrote in the DS 260. They have the petitioner's address, so at this point it's ok to tell the CBP to update with the new address and then my brother could update i it on MY USCIS account.
My question now is if the just fact of an immigrant visa holder who is not yet a Lawful permanent resident nor travel yet to U.S could have this account created without problems . I mean, having MYUSCIS in his name it's not illegal? Thank you!
