Is the location that you complete FRS the same location that you are stationed at for the first part of your career? Also, how long are you typically stationed at any given location?
Some communities only have one FRS, but squadrons based on both (3 including Japan) coasts. If there are multiple FRSs, you get sent based on 4 things: Needs of the Navy, Needs of the Navy, Needs of the Navy, and your preference.
How long you are in a location depends again on community and the four things listed above. I spent my entire, illustrious, 12 year active duty time (after flight school, of course) in Virginia Beach. RAG/Fleet squadron/Fleet Squadron/RAG IP/LSO School/Air Wing Staff. As my buddy Borat would say "Very Nice." I have a good friend, started when I did, that moved about 5 times in the same 11 year period. It used to be bad to "homestead", not quiet as bad these days, but doing the "hard" tours (Japan is primary) is always a tie-breaker come DH and Command Screen.
