Hi. I actually moved here from the UK in 2004 and ended up getting my green card in 2011. I actually did the paperwork myself and it was fairly straight forward. I'm hoping to sponsor my brother for a green card once I get my citizenship. The USCIS site has a lot of useful information.
If you need help finding a home I'm a licensed REALTOR in the Davenport area. You can check listings on my website Vanessa.exitrealtych.com.
Let me know if you have any questions.
