@jickky91 agreeing with my colleague @Opus 17 for his quite complete response, I would like to know three other bits of info. please--
(a) which country are you from ( this is because there may be tax treaty considerations )?
(b) Are you single or married and if married, to whom ( IUS person or another Alien )?
(c) Is your date od departure fixed or is it possible to move -- I ask because in case of part-year resident i.e. dual status filer -- 1. you will need to file by mail ( because of 1040-NR limitation ) and 2. you cannot use standard deduction -- must use itemized and therefore you tax liability mostly will in crease.
I very strongly recommend the suggestion by @Opus 17 that you maintain a bank account, US credit Card and hopefully an US address ( wherein someone can let you know if you have mail from the IRS/State ) ---- at least till the 2024 filing is completely done ( i.e. you have filed, been processed and refunds/ liabilities settled).
Also if you have a lot of assets that are US sourced or immoveable, there may be implications.
I will circle back once I hear from you --yes ?
