To be honest, I don't know. The most straight forward way is for the applicant to use their UCI and their application number, as it is their application in the end. I know some people connect it through the sponsor instead and that seems to be what you guys did given that it's his UCI in the AOR, but I'm not familiar with that. Might as well try all the combinations (both your accounts, UCIs and the app number) - something should work eventually.@np08 The email was for my boyfriend and he has UCI, because I already have an account and UCI, so if I sign in with my account I should use my UCI or his UCI? and yes I put 2, I tried with my information, his information and the number of the application but nothing.
