I'm a Canadian citizen married to a U.S. citizen and have been living in the U.S. as a registered alien for over 12 years now. I've been giving a lot of thought to getting my U.S. citizenship lately. I know I have to take a test and stuff, but I don't know where to get the info on what kind of questions they ask so I can study. Is there anyone that can help give me some info? Any links to websites are a plus! Oh, and I live in the Tampa Bay area of Florida, in case you need to know that.

I have an indoor/outdoor cat that I cannot keep a collar on. She is microchipped, but we have laws here and she is supposed to be wearing her tag that shows she has her shots when she is outside. Also, if she gets lost it will be easier for people to check her colllar/tag than to take her somewhere to have her microchip scanned and I don't want anyone mistaking her for a stray. Please don't tell me to keep her indoors because believe me, I've TRIED! She will not stay in the house! She's determined to go outside and will escape as soon as anyone opens the door to go in or out. Also, she'll sit by the door and meow constantly (and loudly) for HOURS if we try to keep her in. It's enough to make a person crazy! I've tried so many kinds of collars on her, from breakaways to plain leather to making my own out of chain, but she will leave the house with them on and then show up without them! I don't even know how she gets them off! I'm ready to tear my hair out! Please help!
