Master or not??? PLEASE HELP

Hello, I am finishing now my last year of bachelor degree in PT in hungary budapest i want to continue to master degree in belgium leuven university to be able to work in the USA in the future but i am not sure its the right step, maybe i should get my degree evaluated and see what i am missing first and just complete the education the USA because i heard that even with MS degree i still going to have to do post graduated course there. Can someone help me out here and make a suggestion because i dont even know if the degree is accepted there and when i asked FCCPT there also cannot promise that when i be done it will be accepted. PLEASE HELP
