Most important and fundamental step for knowing tax effect under USA tax regime regulated by IRS under Internal Revenue Code is to determine tax residency under US Code 26 . This is because If you are tax resident, law of taxation is differently applied on you than when you are non-resident alien. In that case , completely different provisions of IRC i.e US tax law applies . Further , it may happen that you are tax resident as well as no- resident for the same year. In that case , your status is a Dual Status for which separate taxation law are there in statute book. So, determination of tax residency is most important and actually the first step .
The designation of resident for tax purposes is completely separate from your immigration status. You might qualify as a resident for tax purposes while remaining a non immigrant alien for immigration purposes.
