General Green Card

You only need a police clearance certificate for countries where you have resided for six months or more since the age of 16. Short visits do not trigger this requirement.

Passage of the Bill: It's unlikely to pass the Senate in its current form, despite passing the House. Such provisions often face significant opposition when bundled into larger bills, and there's limited political support for a tax specifically targeting non-citizens sending money home.

Tax Credit Eligibility: Generally, non-citizens are not eligible for most US tax credits, particularly those intended for citizens or permanent residents. While specific tax credit eligibility is complex and depends on individual circumstances and the credit itself, the expert notes that a tax credit component for non-immigrants would defeat the bill's apparent purpose.

A green card holder working two remote jobs simultaneously without their knowledge, receiving two W2s and presumably paying taxes, has likely committed a potential violation of their employment contracts (a civil matter), but it should not impact their green card status or ability to travel, assuming their overall green card history is clean.
