I have created a page with a recommendation for temporary health insurance options for new immigrants., This is especially useful for the period of time when you are activating your LPR status (as you will not want to start an ACA plan) and also for the first couple of months after you arrive to settle before you get a job. It is important to have health insurance coverage so that a medical emergency does not turn into a financial disaster.
I have verified the company I am recommending is providing low cost and sensible options for new immigrants. These plans are not ideal for long term use, but offer a much better option than travel insurance from other countries.
So – check out this page on Health Insurance for new immigrants.
You can also find some information I previously posted about health insurance here.
