If I want to take cash from Portugal to the USA, should I exchange my money before leaving or after arriving?
I would just rely on the salary from my job in the US. If you don't have a job in the US, you're very unlikely to get a visa to move there and look for work, and so the question of how to take money there (except for a holiday) doesn't arise. (Unless you have dual Portuguese/American citizenship.)
