We got our NOA2 on sept 25th and I emailed an enquiry and recieved a response in a few days that had my case number and everything on it. We went online this past friday night and filled out the ds-160 and there was no link to pay any fee. Now we dont know what to do, lol. I think we are still waiting for a welcome letter or an emailed bill for the bank to go pay a fee. We are kind of hanging in standby mode at the moment.
