Are you seeking medical care outside of the country? If you or someone you love already has medical issues that are so extreme you need to leave the country to take care of them, you might want to stop and consider all the details of the trip.
Do you need a passport? When you need to go into a foreign country, you most likely need to have your passport on hand. If you plan to stay a while for medical treatment, you may need to apply for a visa. It is best to learn of these details before you leave the country. One way to find out all the details you need to know is to contact the American Embassy in that country. They tend to stay well informed about such details.
Where will you stay? Do you already have lodging? If your loved one is going to be staying in a medical facility, that is fine for him or her, but you need to make sure you have a place to stay, as well. You might try contacting the medical facility to ask if they can be of assistance with information about accommodations near the facility.
How are you getting there? Air medical transport is probably the safest and most affordable way to go, as long as you choose air medical transport that takes insurance and has no hidden fees. In this way, you can also avoid long lines at the airport, as well. You will also rest easy knowing that your loved one has medical care on hand if needed.
