I am here in the US for 3 years and am planning to change my health insurance because it is very costly. Can I go with visitors plans?
There are certain plans that would be available for you depending on your age and citizenship. However, these plans do not offer as much coverage as domestic health plans and do not meet the Obama Care requirements.

Insurance rates are regulated by law. You can't find the same insurance plan for a lower price anywhere else
