Hello, I am a retired US citizen living in Argentina. I've been told by the Federal Benefits Unit at the US Embassy in Buenos Aires that my Argentine wife, who happenes to be disabled, will be eligible to receive survivor benefits after I die, but will have to spend an entire month in the US every 6 months to qualify. She has never lived in the US and doesn't plan to, so she won't qualify for the 5 year residency exemption. Also in order for her to collect spousal benefits she also has to go to the US every 6 months in order to be eligible. Are there any exceptions to these US travel rules? What type of visa is best for her situation? The Federal Benefits Unit representative mentioned a K visa that doesn't have an expiration date, but I am unable to locate any K visa for her specific circumstances. Thank you very much for volunteering you valuable time. YCombinator is a great source for learning. Kind regards
