Do i have to file a schedule NR if i am a student and earned money in a state I do not reside in?

It depends on which state and how much income you earned there.

we need to know your resident state and work state and type of income like  w-2 wages, self-employment income. .  some states have reciprocal agreements so that a taxpayer will only be taxed in their resident state. in such case, as having withholding in the non-resident state the taxpayer will have to file in his home state and in the non-resident state to get back the withholding.
