I know a Giyores who was specifically told by the Rabbanim who converted her that she had to move from Manhattan to Brooklyn first and live there for a certain amount of time so that she could be exposed to mainstream Orthodoxy before she converted.
While WTP may be right that you should choose your community carefully once you convert, you should also choose your community carefully before you convert, and the considerations may be different.
After you convert, you may want to look for a community that is more accepting and open. Before you convert, your emphasis should be on exposure to the mainstream Orthodox community. Even if it is a bit more right-wing than you may choose to become once you convert, it might be good to have some exposure to it now.
Of course, those two “types” of communities (openminded & accepting vs.mainstream) could coincide in any case.
It sounds like you may not have a choice right now anyhow, but it would probably be a good idea to visit other communities for Shabbos, etc. in order to get a broader picture of the Orthodox world (which is confusing enough even for those who were born into it!).
Hatzlacha! It’s a big step to take, and kol hakavod for choosing it. I hope you find a wonderful community to grow and learn in.
