{{ In 2022, we traveled so much that I was outside the US for 11 months, thereby qualifying as a US nonresident. This meant I could sell all my stocks, without paying US capital-gains taxes. }}

Filing a return (of some type) is required for people (US citizens or not) who claim US residency. That might include not being required to file a return but rather to notify the IRS (on their form–whatever it is) that you were not a “resident of the US” (per IRS rules) for that year. Talk to a tax pro who specializes in this area. Worth every penny spent.
