I saw that for spousal sponsorships without any dependents that there isn't a required income, but on the Document Checklist part B question #5 you must provide proof of income or ability to support. When I move in a few months I will most likely continue to work for a US-based country remotely as I tie projects up (and my taxes from the past year are from a US-based company). Would having my taxes come from a US company still work with an inland application?
