In the Documents Cheklist-Immigrant, under point 9 it says: "If you are being sponsered by your spouse...you must send evidence of the relationship between you and your sponsor such as wedding photos...", so, strictly speaking, it would be enough to send ONLY wedding photos, isn´t that right? I´m asking because I was reading here, that many people sent dozens of pictures, also from holidays, birthdays etc. (I will be sponsoring my husband from abroad, we have to small children)
