@Edward and Jaycel
So the tax transcripts should be good enough. Because the letter i got from abu dhabi mentioned company letter and my company isnt providing one for K1 visa(idk why). But im thinking since they want proof of employment, Tax transcripts should be fine. Just was confused about what is required because they mention:
An affidavit of support From I-134 should be completed by the petitioner and submitted with all supporting documents - current salary letter, current bank statement and 1040 tax form for the most recent year.Originals, not photocopies, of these documents must be brought.
Originals was throwing me off because i only have a PDF version
