hmm...quite a dilemma u got there...i agree with most of what they said here..it would be much better if your fiancee could secure a job for you in the US...keep in mind the cost of living in the US is much higher...does your fiancee have a secure and stable job there? if so, then you could go there and look for work....but if you're fiancee still just starting to settle then better wait...and just save up...
either way, both love and career are hard to find and keep, just keep in mind most people who chose to work spent most of their lives looking for love...and most of those who chose love over work are now looking for work...but the big difference maker between the two is the age at which they chose which is which, and the reasons...in time you will figure that out..good luck!
