Resident is not the same as citizen, which is what OP mentioned. Having "resident" status in a country generally gives you many perks of being a citizen without actually becoming one. Usually things like being able to open a bank account, working legally, getting a drivers license, etc. with the "liability" of possibly having to pay into the equivalent of social security (and other things, can't vote for example).

This does not change any citizenship status on either side.
