[MaigicyuNinia]

I think it has become very close to Fard for French muslims to do Hijrat immediately.

Why french only , firstly for the muslims in Belguim.
Belguim was sad enough the first country to ban niqab , but the true fact is you just can't blame them if it could be banned in muslim country's then why not in country of disbelievers.
One thing to be remembered The wujoob of niqaab is only in the hanafi fiqh so it would become fard according to us , but according to many fuqaha it's not waajib so hijrah wouldn't be fard on them.
May Allah swt make the sittuation for all the muslims eassy , for sure it's a effect of my sins.

jazakallah
