Studying abroad can be hard. You will probably have times when you miss your family, friends, food, and everything familiar. Almost everyone goes through some culture shock. You will have to realize and accept that it will take some time to adjust to a new way of living.

Studying abroad can be expensive. There is no doubt that it takes money to study abroad. It can vary from kind of expensive to very expensive. Most places don't allow international students to work. You will have to have the money before you arrive in the country or have someone from home support you. Is this something that you and/or your family can afford?

The disadvantages are the standard of living and free-friendship. The cost of living in other countries is quite expensive, so we need to spend more money on it. Moreover, the free-friendship means you can have friends and do anything freely, but the problem is about free-sex and so on.
