Each case is different and the requested documents can vary. Indicatively, here is a list of the most common ones, if you want to start gathering documents for your case:

• A copy of your birth certificate
• A copy of your passport
• A copy of your current and previous Visas if there have been any
• A copy of your marriage certificate
• Photographs, tickets and any other proof showing that you have a real relationship
• A copy of the US spouse’s citizenship documentation (US birth certificate, Certificate of Naturalization, Green Card etc.)
