Prohibit immigration into the UK from any Country who may pose a threat to UK

Prohibit immigration into the UK from any Country who may pose a threat to UK National Security irrespective of prospective immigrants' status. Government has a duty and responsibility to protect its citizens from any threat irrespective. The rights of the many outweigh the rights of the few.

Petitions need to call on the Government or Parliament to take a specific action. We are not clear what you mean by "pose a threat to the UK". You could start a new petition explaining clearly what you would like the Government or Parliament to do.
