"In-state residency" requirements?

You should be more specific in regards to what you are asking. While Gooddwill is correct about the college residency, there are other residency requirement for divorce, marriage, etc. For example, Kansas law require that you live there for 60 days prior to filing for divorce. Some states like Virginia require 6 months. Others like New York require 1 year. In regards to moving, you are normally required to change over your driver's license to the new address within 10 days, and car plates within 30 days.

Since your question is under immigration, I am trying to tie it in with the immigration laws. However, immigration laws are federal, and are pretty much the same for all states. There are different numbers to play with -- 2, 3, and 5 mostly. Illegal aliens who can prove that they were in the US for 5 years can generally begin the process for legalization.

Not sure what really you are asking, so it's hard to answer...

In state residency for what?

I can tell you that in California, as far as driver's licenses are concerned, as soon as you get a job you're considered a resident and your out-ot-state license is only valid for 10 days from that point. As far as college tuition is concerned, it's much more complicated. But in general states will set their own policies for who is a resident, which may be different for different purposes.

Are you referring to resident status in regard to college tuition? I don't think employment has anything to do with that, it's more that you can prove you lived there...bills in your name, bank accounts, etc. In Colorado, where I live, it is one year living in the state before the first day of class.
