@nalor511 I got a Maryland license at my mom's address and turned in my North Carolina license. This was easy for me because the only car we own is registered to my wife and we didn't own a primary residence at the time so this didn't creat any incompatible conditions for our insurance company. To them it simply looked like I was moving out. Once I acquired my MD licence I moved my bank accounts and credit cards back to my NC address. While I'm technically in violation of not changing my license back to NC within 60 days of "relocating" there's no one to care or enforce because there's no car in my name.
@ohsnap while the state of Maryland could try to argue that by getting a MD licence I am now a resident of MD, I would counter argue that I move there and then immediately moved back to NC. My voter registration is still in NC, all my important accounts come to a mailing address here, and I physically live here. I don't think they'd win in an income tax audit. So I just continue filing non-resident MD taxes there as I was already (for a rental we own there).
