An obvious disadvantage is that it will impose heavy financial burden on parents. If we are born in a humble and ordinary family, it is difficult to afford the cost of staying in a foreign country for a few years. Studying abroad, we need to pay for the expensive cost of living and school fees. Unfortunately, some of us may not be able to meet the huge cost. If we are so determined to study overseas, we may need to do part-time jobs while studying. We and our parents need to lead a harder life.
