Whatever you do, don't get a MD car registration without a MD license or vice versa--MD will ticket you (it happened to a friend of mine). Here is a list of MD MVA fees (
MVA Fee Listing). Unless your job requires it, consider moving here without a car for awhile--it's not NYC, but METRO will get you most places you want to go, and you can wait to see where you end up before you get a license. You'll also find parking in either downtown Bethesda or Silver Spring can be expensive.
