You can still translate it into 簿チ because 簿チ猭 also covers regulations and procedures for non-PR students.

Foreign students are usually holding non-immigrant visas. Even if they do not intend to become PR after they finish their study, it is still advisable for them to know immigration laws and regulations. If they violate some immigration regulations when in school, their study in the country may be terminated immediately.

For example, U.S. immigration regulations specify that foreign students must register as a full time student and take enough credits in each semester. They are not allowed to work off-campus unless approved by the immigration services. If they violate those regulations, they may be deported out of the country. I believe the UK immigration regulations concerning students are similar to those of the United States.

换言之，移民法管着所有的外国人，无论是移民(永久居民)还是非移民，无论是合法入境者还是非法入境者。

“ immigrate” is not equal to “naturalize”。

In your context, this should refer to the general procedures for becoming a resident.

入境is more focused on physical entrance, not the legal procedures one has to go through, including applications and getting approval.
