One thing I would definitely recommend though is getting a physical(I-693) before any formal regulations come into play. You never know if anything might come up and if it does it is better to get it treated before it has to be formally filled anywhere (...and I'm not even talking about STDs). For example, a lot of people can have a positive TB virus test, only to find out it is in an inactive form or you got the BCG vaccine as a kid, but they will make you get an xray anyway etc. only to tell you that you don't have it.

I know a lot of people here don't have HI, so if you do it now, you might be able to find cheaper doctors, instead of having everything done by a Public Surgeon.
