discuss quota systems-what is it, why? purpose? is it still in effect? what forms?
The quota system in immigration policy mandated that only a number of immigrants could be allowed from each country. Those who endorsed this policy wanted to keep the ethnic and religious makeup of the U.S. as it was at the time this doctrine was established.
At this time the quota system is not based on country of origin, but on other factors.
