You may not feel like a stranger, but some things may have changed in your home country since you last visited. For example, you may need to consider new requirements for health and safety. And you will need to purchase visitor insurance, even if you are originally from the country you are visiting. Depending on your circumstances, visitor insurance is required for visiting the US.
If you have been living outside of the country of your birth for many years, you may be surprised to learn about new vaccinations that are required to return to your home country. New recommendations for safe travel may also be in effect.
Traveling to the US from certain countries may require certification of vaccination for diseases. Make sure you know what you need by visiting a travel medicine specialist.
Insurance is also needed, even if you are a US citizen by birth. If you don’t have a US health insurance plan you will be stuck with high medical bills if you are sick or injured in the United States.
