Aperson who is in favor of greatly restricting immigration because it takes jobs away from american citizens is called a sectionalist abolitionist activist nativist

Nativist is the correct option.

Explanation:

Nativism is an American concept. It originated in the mid 19th century with the political movements in US. The Know Noting Party  was an american party which followed this philosophy and portrayed catholic immigration as a threat to native protestants. The nativism emerged naturally as an opposition to the migrants.  There is no clear definition of Native in the American context as most of the Americans are migrants themselves.
