I am in the same boat as you @Keepit; recently got married and would like to submit the application process ASAP.
Here is a checklist that would help in the application process. It is just a guide and doesn't have to be exactly as mentioned. My most pressing issue is how to prove my marriage is bona fide as we got married very recently and don't own any joint property or bank accounts and my talk with the bank here at US requires her to be here with at least two form of identification. Also, is the copy of Beneficiary's passport required?
Anyway, gudluk bro. I for myself, have decided to use a lawyer, even though, the process is pretty much straightforward.
