Yes. The instructions say to upload it. I would scan and upload the complete document (Public deed of divorce), and take originals of all civil documents to the interview.
I live abroad with my wife. I work 100% remote for an American company. I filed the FEIE this year. Employment will continue once I move back however I don't know if I could get a letter to that effect. HR is very protectionist. My assets are well over the minimum requirement for sponsoring.
What do I need to do to:
1) Show intent to establish domicile in the US
2) Make sure my income / assets are sufficient for sponsorship
Unfortunately, I have a lawyer but the original lawyer I hired who knew about FEIE became a federal judge and transferred the case to someone who's fresh out of law school.
