Many factors determine whether being an exchange student is a good choice. No matter which exchange student option you choose, grades, finances, health, diet, religion and politics all influence your ability to fit into a new culture by yourself.
The most important factor involved in making your decision is that you must realize that once you have left home to travel to a new destination you are all by yourself. Everyone in your new culture will judge you based upon the cultural rules they understand. No one really cares about the rules you grew up with. Not your host family, not your international coordinator and not the school you attend. Usually people will cut you more slack than their own young people, but theirs are the rules you must learn. Even if the people you live with are related to you, you will still be judged by the cultural rules that apply to their family.
The schools you attend will be in a completely different language. All of your subjects are in a different way to what you are used to. The grading system might be a bit different. You need to have AT LEAST a C average to even consider going. A higher grade point average makes adjusting easier. If you have a D or F average, you need to forget about going or work hard to change it.
No matter how you travel as an exchange student, it will cost you. A lot of money. Travel fare, passport, visa, tuition, housing, food, pocket money, clothing, vaccines, and so on. It all adds up. If you travel with an exchange organization, they will take care of the plane ticket to your destination and getting you a representative. In some instances your fee goes up because they pay the host family for having you. Even if you travel with an exchange organization and the host family is free, you still need to pay for passport and visa, pocket money, any special dietary needs, travel to the airport, clothing and so on. If you estimate using at least 10 000 Euro/USD all together, you have a starting point. How will you get that money?
Sometimes stipends are offered in the host-country or by the country you are travelling from. Your parents could be well off. Maybe you need to save up to it. If things turn bad, you risk losing all that money. Especially if you travel with an exchange organization. Are you willing to take that risk?
Any country you travel to demands that you be of good physical and mental health. Some countries require vaccines. You will have to do a physical, pay for insurance and answer lots of questions. Remember to be honest. Allergies, ADHD, Aspergers, dietary requirements, diabetes, epilepsy, and so on. Be honest. It could go very bad for you if you lie.
If you struggle with PTSD, eating disorders, depression or anxiety, it is likely that your mental health problems will increase. Why? New food, new cultural rules, new family rules, and so on affect mental problems. In rare cases I have heard of people becoming better, but in those cases their home family situation has been far from ideal.
If you are travelling with an exchange organization, and have informed them about allergies or other sensitivities, you still risk being placed in a family you shouldn’t be. How would you deal with that?
Vegans and vegetarians have a harder time being placed. Particularly vegans. You will most likely have to buy and make your own food. Can you handle living with a family that eats meat. Most families you end up with do. If your religion has particular dietary requirements, how will you handle that?
Many students struggle with this aspect of life, particularly if they end up in a place that has the opposite view of theirs. Sometimes the conservatism is so strong that it becomes abusive. Whether that conservatism is Muslim, Christian, atheist, Jewish or any other choice out there, ending up in a belief system contrary to your own requires a lot of an exchange student. Will you be able to keep your mouth shut and remain polite? Too many Muslims are placed into conservative Christian families who try to feed them pork products. How will you handle an abusive situation?
New cultures mean new political points of view. Who is to say that yours is better than theirs? They won’t think so. Will you be able to refrain from criticising people who have wildly different political views?
These are some of the things you need to think about before you choose the exchange student life. It could end up being an amazing year but might also end up being terrible.
