@janar, it looks like you already found the request an appointment form for Mayo Clinic here: http://mayocl.in/1mtmR63

During the submission process, you will be asked if you live outside the US. The next step will be a telephone appointment with a scheduler to find out more. You will be able to ask about cost and insurance coverage and other questions you may have. When you speak with the scheduler, please ask them about translations of medical records. Your English is obviously very good, but I wonder if medical institutions, including Mayo Clinic, might require medically certified translations.

Every year, patients from more than 150 countries travel to Mayo Clinic for care. Here is more information about International Patient Services at Mayo https://www.mayoclinic.org/departments-centers/international
