URGENT INFO RE: GCKEY + linking. I linked my GCkey as a Sponsor to PA's account # after many tries>OK. Then PA also linked her same account number to GCKEY> OK. But I got e-mail , saying "This account is linked by some 1 else." Also happened both ways. In other words now it is clear that either Sponsor or PA can keep linked to the same application number at a time NOT both of you. Any comments or experiences are welcome so we learn from each other. What if they need something from Sponsor? Will PA upload? And Vice-Versa. Or it does not matter. OR any method to keep both guys linked PA to her app account no. and Sponsor to his UCI only ? Thanks 4 replies.
