Thank you @DaveF1006 for the very detailed reply. Question in regards to my spouse's foreign income if jointly filing: file her worldwide income by filling out a W-2 form? (they may have a different form and blocks on the form) Where in the tax forms do I add the taxes she already paid in her country on her income? And where do I add in the tax forms her foreign savings/investments and gains/losses? (She has zero US income+banking,+investment,+property, etc. ) Thank you!
