I am currently in the US under a J1 and my home country has a tax treaty with the US. Therefore I am currently exempted from federal taxes and some other taxes.
I am getting married soon and want to apply for an Adjustment of Status. My question is, how does this affect my tax status for the current job (J1)? Will I have to pay taxes for whole salary I earned or is this still "tax-free"? Is this different if I would apply for AOS at Jan 1st? When does the Tax exemption end?
Edit: Tax treaty Germany USA Article 20(1):
- Remuneration that a professor or teacher who is a resident of a Contracting State and who is present in the other Contracting State for a period not exceeding two years for the purpose of carrying out advanced study or research or for teaching at an accredited university, college, school, or other educational institution, or a public research institution or other institution engaged in research for the public benefit, receives for such work shall be taxable only in the first-mentioned State. This Article shall not apply to income from research if such research is undertaken not in the public interest but primarily for the private benefit of a specific person or persons. The benefits provided in this paragraph shall not be granted to an individual who, during the immediately preceding period, enjoyed the benefits of paragraph 2, 3, or 4.
