A plan is always needed. This can include where you want to live, what you will do once you get there, how to find a community and create a suitable living situation. Not having a plan and just winging it may not be the best use of your time.
Finding a job is one of the most important things when living as an expat. Nations do not want people to drain their resources without contributing. Many countries will not let people stay unless they have a visa or some income coming.
Each country is different, especially with visas. Just because you believe your country is the best means, it will be treated the same in other countries. Visas are essential to enter and live in a place.
Moving to another country is not always the easiest. You will need to let family and friends know of your decision. They can be tremendous advocates for you and give you aid with research.
Going traveling usually requires money. Not having money can bring about stressful situations. Banking can be the thing you should work on next. One of the best things is to research a bank account that is international or has fee-free ATMs.
