Is it possible to get global medical insurance?
Yes, global medical insurance products are available and there are a lot of different companies offering them. Global health insurance differs from travel insurance, as it is more suited to long term travelers such as expats and international students. When I moved abroad I found this company, https://www.now-health.com/en/global-medical-ins..., that offered insurance for international students.
If you are unsure about which insurance packages you need when you're going abroad, it's always a good idea to ask for help. You can ask people that have similar circumstances to you about their coverage. You can also call companies, and ask for more details about the packaged that they offer. It's important that you choose the right package, as you need to make sure that you are covered for everything if you are planning to live, work or study abroad. Lots of people forget to take out insurance, and it can end up costing them a lot of money if something goes wrong health-wise.
