There are some very serious tax consequences to changing your citizenship (or becoming a dual citizen).  It depends on the country you are talking about, exactly what the consequences are.  But its not something I would rush into without looking at all of the impacts.  I travel quite a lot for my job, working for a large company that is internationally owned, and I have never felt any desire to change because of work.  But if you fall in love with the place, and want to be a dual or permanent citizen, then it might be worth the hassle.

You don't say whether you became a British citizen, but as far as the birth certificate goes, you can always request a duplicate from the state where you were born. I don't know what's involved in that, but it's possible. My own is a duplicate (my parents got it for me, so I'm unclear on the details).\n\nAs far as all the ID/passport stuff goes, it can't hurt to contact the US embassy or consulate. This is their area of expertise, so just ask them for their help and they'll give you the right info.\n\nGood luck!

There is a process (and eligibility requirements) for becoming a US citizen. Check out the Immigration and Naturalization web site.\n\nCounty web sites advertise jobs available in their departments, including police. Some counties may not keep their web sites up to date in careers. In some counties, Police departments may have their web sites where you can find this info.

Both of the above answers are correct.\n\nThe process is fairly simple in most states. You go down to either the local county courthouse, or the county clerk's office. There will be a standard form to fill out, and you'll need to provide ID and probably a copy of your original birth certificate. The fees vary, but are usually under $100 and some states are as low as $25.\n\nSome states require you to speak to a judge who approves the change, but not all states do. Once your application is approved, you get an official notice of the change in a few weeks. After that, you need to update your drivers license, birth certificate, etc., all with the appropriate agencies.
