Hello. I'm planning to get a green card after winning in DV lottery and become a US resident in August 2025. Currently I live in Serbia and work for a company here. (as I understand Serbia doesn't have tax treaties with the U.S) , and planning to work here up until March 2026. I'm planning to enter the U.S in August, stay there for 3 weeks and leave back to Serbia (planning to stay 3 weeks only in the U.S in 2025) . Do I need to file my taxes on income from the beginning of 2025? Or from August 2025 (date when i become LPR) ? Am I eligible for foreign income tax exclusion (I pay taxes in Serbia)? Am I eligible for Standard deduction? Am I going to eventually end up paying double taxes in the U.S and Serbia? (In 2025 I'm going to make around 40000 USD gross for the entire year and pay 10 percent income tax in Serbia) If yes, are there any ways to avoid it?
