Answer:
Laws and rules have changed through history.
Step-by-step explanation:
During the last few years, laws and rules for immigrants have changed owing to the fact that for many years "immigrations laws" have worked to exclude immigrants in the past. The government regulated immigration soon after it won indepence from Great Britain. As an example of this is when no white people were excluded. They couldn't live more than 2 years in USA. However, in 2012, some rules and laws changed owing to the fact that there was a new president called Obama who allowed the permanence of young adults in the country and he also allowed that those people could work in USA.
