There's no country which has expensive Medicare than US. So, if you're trying to use your situation to get a faster route to US, think twice. It's not a good idea.
And I agree with everything @Carlos.Brazil said.
Wanna know how expensive it is? I went to the dentist 1 month ago and they never did anything other than take a scan. After insurance did their bit, I paid $300 out of pocket. My teeth weren't fixed. I was in an out in 10 mins. Just the $300 alone could have solved issues if I'd have gone outside the country. Doctors charge for anything here, even breathing in their office. So, go somewhere else. US isn't that rosy.
Did you by any chance mention to your doctor that you have a US petition or want to obtain a B-2 to go to US or something? I really doubt if he just blatantly told you to go to US, out of the blues. A lot of USC here are going to M.East and Italy for Healthcare.
