My sister-in-law‘s partner won the lottery, did her interview and received her visa in the mail this week. They were planning on coming to the United States to get married and start the immigration process, but didn’t realize that it takes several years for the spouse of a permanent residence to even partake in an interview to adjust their status. My question is a lawyer suggested getting married and resubmitting the paperwork together so they can both come at the same time. This seems highly risky but wanted to check if anyone has experienced something like this or has any insight.
