Hello,
A friend went for a spousal interview and was given a paper with section 212(a)(6)(C)(1) marked as the reason for the refusal. He is eligible for a waiver. In 2011, his then girlfriend won the dv Lottery and they got married after. The CO denied the visa because she didn’t believe they were genuinely married resulting in a section 212(a)(6)(C)(1). Does he need an immigration lawyer to file the 601 waiver or he can do it himself? Thank you.
