Hello, I'd like to ask for help: My fiance (US citizen) and I (H1B holder) plan to get married at the end of this month (August). We plan to file I-130, I-485 and I-765 early September. My question is: Would it make it difficult for me to use his last name instead of my maiden name on the application forms (with just a copy marriage certificate as a proof)? Should I apply using my maiden name and change my name later after my application gets approved? Can anyone please help? Thank you so much!
