My wife emigrated to the USA on a K1 Visa in September 2019, and we got married shortly thereafter in October 2019. Prior to September 2019, she had worked in the UK from January 2019 until August 2019. Right now we are filing our 2019 tax return jointly. Do I need to report her income earned in the UK? If so, how should I go about it? So far, I only have her P60 document, but that is from April 5 2018 through April 5 2019.
