My wife and I have been married for over 4 years. I am a born American Citizen and she is a Costa Rican Citizen. We spend most of our time in Costa Rica but I maintain my residency in the United States and we travel back to the US (Northern Virginia) together about once every 30-45 days (for about a week or 10 days). My wife is an accomplished attorney who established her own office 12 years ago and I am a international relations policy consultant. She has a 10 year visa B1/B2. We were told that since we do not both “live" in the US it will be difficult for her to apply for citizenship. However, we were recently told that since we have been married for over 4 years she will be able to apply for citizenship while we are abroad. We both have clean criminal records and are professionals. Can you please advise on the best pathway for her to get citizenship? Thanking you in advance.
