restricting the number of immigrants into the country
Quota System
Europe or Mexico Answer: That would depend entirely on what country you are inquiring about as the "recipient" country. Europe is not a country, so that's definitely not the right answer.
Mexico World War I (WWI) brought immigrants from various countries, but the most number of immigrants came from one country; and that country was Mexico.
To calculate the immigration rate, divide the number of immigrants arriving in a country by the total population of that country, then multiply by 100 to express it as a percentage. This will give you the rate at which immigrants are entering the country relative to the total population.
Yes, we do. Most immigration acts are built to limit the number of immigrants. There are standards each on sets for the acceptance of immigrants. One example is an act that bars immigrants from entry to the country unless they have family ties.
