To find out what steps you should take to move to an overseas country, visit your local consulate. Ask about long-term visas, and whether the application process has to be completed before you embark on your move. These laws vary from country to country, so it is important to inquire about the specific requirements for the country you want to move to. If there is no consulate located near you, contact the U.S. government with your questions at https://www.usa.gov/contact. Alternatively, contact the government where you live. The US government can't help UK citizens move to France for example. Most travel visas last no longer than 3 months, making them unsuitable for a move overseas. Visit your local consulate to get the proper paperwork to apply for a work visa. As a general rule, the application process either requires that you prove that you are working at a job that is sending you overseas, or that you have a job lined up for when you arrive in the country.  Have your current or new employer issue official proof of employment to you to present to the government. You can also apply for a temporary residency if you do not have work lined up. The STEP program allows U.S. citizens to enroll with a local embassy or consulate when they are travelling or living abroad. As a member, you will receive information, assistance, and the possibility of contacting friends and family back home in an emergency.  Visit https://step.state.gov/ to enroll. If you are not a U.S. citizen, look online for a similar program in your country. Most medicare and insurance policies will not cover the cost of overseas medical expenses. Ask your insurance provider for a quote on high deductible policies that would cover your medical fees abroad, or look for an insurance provider in your new country and get a quote. Research the cost of paying out of pocket for different everyday or emergency services in your destination country to compare costs. Do research online to see if your medical fees might be covered by your new country's government. Moving to a new country can have financial implications due to the change in currency and distance from your own financial institution. Contact your bank as soon as you decide to move to work out the details of your overseas financial situation. Depending on the institution, your bank may still be able to serve you without drastically altering fees or account settings. You are bound to receive mail after you move overseas, which will end up at your former residence or get lost. Visit the post office to redirect your mail to the address of someone you trust to open certain correspondence that might be important. Alternatively, you can register for a mail forwarding service, where an employee will scan your mail and open it for you whenever necessary. After moving, be sure to address your tax requirements by consulting government resources or getting professional help. Contact the nearest municipal tax office in your new country or visit the department's website to get information about filing requirements and deadlines. If you are unsure about how to proceed, hire an accountant or tax preparation service to file your taxes for you. If you are a U.S. citizen moving abroad, visit https://taxmap.irs.gov/taxmap/internationalindex.htm to search for specific information about your taxpaying situation. Depending on where you are moving overseas, it might be necessary to complete your immunizations before you leave. Visit your doctor several weeks before your move so that any vaccinations you may receive have time to take effect in your body. Your doctor can provide you with an  International Certificate of Vaccination booklet, which may prevent possible visa complications down the line. Visit https://wwwnc.cdc.gov/travel for more information about what you should do to safeguard your health before travelling to your destination country. If you are moving to a country that communicates primarily in another language, take the time to learn basic words and phrases before moving there. In emergency situations it may be beneficial or necessary to communicate clearly. Buy language books or software, visit translation websites, or take an introductory class to learn the fundamentals of the language.
