the argonians are allowed to enter the city, one can be killed in the market by the butcher if you're too slow. they're just too poor to move out of the assemblage their boss provides for them.

The Dunmer though... their is a bit of a debate on whether or not they are citizens of skyrim.

though the reason Ulfric doesn't like them is because they insult his cause, beg for assistance, and they don't really help out the stormcloaks or the people of windhelm.
