Were you warned ahead of time how long the process might take?

Texas, California, Florida and New York are probably some of the worst states for trying to gain your citizenship. Montana, Minnesota, and Wyoming are probably some of the fastest. You applied in a state that has a massive population to start with. It also happens to have a big problem with illegal aliens, as you pointed out.

You also weren't forced to do it.

Did it take a long time? Sounds like it did. Did it cost alot? Sounds like it did. Is it worth the trouble you went through??? If your answer to that is "yes", then you really shouldn't complain.
