Immigration has always been difficult. When people immigrate, they leave behind their friends, families, and culture. They also have to sell what they have, like a house, farm, or anything else too big to bring. Immigrating is also difficult because of the strict Immigration laws and qualifications within each country. It is hard to become a legal citizen of a country. It takes time (about 5 years in the US) and a lot of patience to become legally apart of a country. (USA-GOV pg. 1)
