For my flight I transferred AMEX points and got a frequent flyer one way. I put my whole life into three suitcases (paid $300 for checked bags) and donated the rest to goodwill. I’m so happy for the excitement around here. Things may get tricky- it is the same language but it’s not the same country and things at first you may miss (decent Mexican food, but because I’m half Mexican just make at home). Learn to be ok rebuilding credit and having to take a driving test again (although you can drive on your US license until you get it converted). Just keep your head high. Also, if you still have credit card bills or student loans in the US, use transferwise. I paid a fortune to transfer funds to the US but then wised up.
