How do you file a US tax return when your spouse lives overseas? I was asked this question by a reader the other day and I thought I would try my best to answer it in its own post! If you’re going through the USA spouse visa process, the chances are because of how long it takes, there’ll be a time when you need to file taxes when your husband or wife still isn’t living in the country. My reader was concerned about how the NVC (National Visa Centre) would view their marriage by the way they filed and if they’d need to apply for an ITIN number. This is how we filed ours in 2016 for the 2015 tax year and how we managed to satisfy both of these queries.
