No teacher.

What makes you think that your sentence is not good?

Well, there are always other possibilities.
You could also say:
A lot of people think immigration policies should be stricter.

But as said, there are plenty of other possibilities...

May I add it also depends on the circumstances?
E.g.
1)You are talking/writing to a friend (informal context)

A lot/Lots of people think immigration policies should be stricter/more strict.

You are giving a talk/writing a formal text (letter, essay, etc...) (formal context)

Many (people) think (hold, maintain, find ...) that immigration policies should be stricter/more strict


Hope it's clear.
