I am going to discuss insurance with my employer. It looks like it is a pretty big deal in the US.

We've visited several countries in the past. So, cultural differences should not be a big problem but since so many people are emphasizing on this point, I think I'll come and stay for a few weeks as a worker rather than as a tourist and check it out again.

3 is definitely what is troubling for my family which is used to such comforts now.

Thanks for all your inputs!
