Being an expat means that you can move to another country that might be far from where you are originally from. Some expats relocated because of work. They end up staying if they decide that they like the country and its culture. But relocating to another country is not that easy. There are also considerations that you have to think of before making up your mind whether to stay or not.
One of the considerations is the medical facility. If you have a pre-existing medical condition that needs maintenance or regular treatment, then you have to find out if the country can offer that for you. What you are getting from your country may not be offered where you are planning to go. Inquire if your health insurance can be used in other countries. It would be better if they are a provider that is affiliated with other companies worldwide.
There is also the language barrier issue. If you speak a language that is not English, it may be difficult for people to understand you and vice versa. Get to know the country you are relocating into. Do they speak your language? Are you willing to spend time studying and learn their local language? These are major things to think about.
Another consideration is the cost of living. People living in Europe and in the US find living in Asia or Africa can be fairly inexpensive. This is due to the difference in the foreign currency being used. The high conversion of local currency versus Euro or Dollars is a big advantage. A one-month budget can last for months in another country.
Food is also a big consideration. There are expats that are particular to the food they eat. While others can easily adapt to the different tastes and spices of different places. If you are particular about the food that you eat, check to see if there are local restaurants that offer food that you are accustomed too. Or if the local market sells the ingredients for recipes that you can cook yourself. The majority of expats get used to the local cuisine or menu of places they are at, in time.
Planning to be an expat and living in another country can be an exciting change from the normal. Despite the differences from what you are accustomed to, you will find that there are also a lot of things to love when you move. It might be good weather, friendly people or exotic destinations. You just have to be certain that you have everything you need on hand. And that the advantages outweigh the disadvantages of being an expat.
