RaxDFW;
You really should re-read what Real and ShyBoy have already written in this thread they're giving great feedback based on personal knowledge.
If paying for Dr. visits in the US, generally $5 to $50 co-pay each visit, isn't thrilling you you are going to love some of the other "culture shocks" you'll have here.
1. Everything is done through credit down here. No credit no apartment, no car, phone, heat, water, lights.
2. You need an SSN to get paid, get an apartment, etc. and it's taking months to get that # now compared to weeks prior to 9/11.
3. Food is way more expensive than in Canada
4. Many people commute 2 + hrs/day roundtrip to jobs
5. A car is likely more of a necessity in Texas than in other states; you'll need credit to get a car see #1.
OHIP will know you're in the US the first time you send back for reimbursements.
BTW, you do know that you have to pay the full medical bill first, then seek reimbursement at Ontario rates? Again, read ShyBoy's post....
