The lady who checking the documents quite rude. She asked for tax transcript but the email the sent me didn't any mention tax transcript just tax return. She said that i didn't READ MY EMAIL correctly, too bad i didn't print the email so i can't show her.
Then the american officer interview me. He was so nice. Easy question. Probably just 5 basic question. Then he about to approve me but the lady in the first place who checked my document still insist i need the tax transcript so he didn't approved me. I should submit what i lack first. Then i called my fiance and he just email it within an hour. Problem solved. And got approved the next day.
