@Abu kamara You will either fill out DS-160 or DS 260. The documents needed should be stated on your NVC welcome letter. If you don't have the letter once you log in to your CEAC account it will tell you what documents to upload.

@William u my case was sent to the department of state and I have a lawyer on my case

@Abu kamara It's good that you have a lawyer, now start working on gathering all the documents. The you submit the faster they approve your documents.

William u I have submitted my financial tax documents to the lawyer and the affidavit of support
