There's tons of threads for tips and tricks. If it's just you and applicant, did you put 2 for number of people?I received my AOR1 for both myself the sponsor, and my husband the applicant. BUT, I've tried linking the application online, and have maxed out 5 times 2 days in a row. NOTHING is working, is anyone else having this problem? I live in the USA, so I can't call them. What do I do?
Also, don't stress. Not only is linking not mandatory, it does not change the process, and you can do it at any time throughout. If you miss the 7 day "deadline" it's not a big deal.
