enforce the hijab to become

But the police have found that as European fashions have influenced Iranian women's tastes, enforcing the hijab to become/is becoming increasingly difficult.

What would you here, to become or is becoming? Thanks.

"is becoming", "to become" is ungrammatical here as it is missing the verb (is), and in any case the situation is ongoing, not in the future.

Matching Mole is right, is becoming, is the only correct choice.

I wrote to correct another mistake.
