My husband is also a british citizen. The best thing for you and your husband to do is to contact an immigration attorney once you get to the US. When my husband came over, he came on a tourist's VISA and we decided to marry before he went back. An attorney filed all the paperwork for us. It is somewhat time consuming and you want to make sure you do the paperwork correctly so they don't send you back to the UK! You can get a driver's license as soon as you have been approved for temporary residency, usually 30 days after starting the paperwork. It cost us about $1,000 for all the paperwork that is required along with attorney fees. Your husband, being a citizen, needs his passport, and I believe you just need an I-90 - but please, check with someone in the city you will be staying in. There are immigration offices in most of the larger cities and attorneys available to help.
