You have changed the question. : - ) If you say that under some circumstances Hijrah becomes Wajib then we have no problems with you. We are discussing general blanket rule "Hijrah is OBLIGATORY on Muslims from Non-Muslim lands to Muslim lands" Blanket Fatwa. P.S: I can categorically prove to you in the Hanafi Madhab Hijrah DOES NOT become wajib even if they ban you from Hajj and I will quote you text later and don't forget that Hajj is a Pillar of Islam.
