Who to choose?

What if she marries a guy in IL and after 6 months they have to move because of his job (or whatever unavoidable circumstances) ? Will she apply of khulla/divorce?

In essence, moving/no moving should not be a Issue in bigger picture. She should consider other factors instead of making this a key issue unless of course guy lives in lets say Rawanda or Afghanistan etc. I am assuming that he lives only in different state of US
