I think I might be running a record for I-797 (17 Dec) thru receipt of packet 4 (31 Jan)

Very very excited indeed although it does leave me with two questions so if anyone has any guidance that would be great

If I have a date does that mean paperwork, searches etc at this end has been approved and it is now just down to the interview or do they contunue to process application whilst interview appointment is pending?

What is the likelihood of anything going wrong at this stage?

Oh and one final question, is it worth badgering the embassy helpline to see if it is possible to get a cancellation from somebody else and get the interview done slightly sooner?

i have medicals done, police report, affidavit of support and everything else ready so no issues there

I dont have anything to hide or a bad background or anything like that but as soon as you see the finish line you start to get paranoid about falling over
