How about a “duty” NOT to “migrate” if they have no LEGAL right to “migrate” where they are migrating to.

Again, he speaks with forked-tongue by denying the other half of the issue and addressing only part of the issue when it comes to DUTIES.

Said the Pope, "every country had the right to regulate the flow of migration"

You do nothing but seek to smear mud on the Pope and attempt to imply that he favors illegal immigration. Please, check your facts before launching mindless attacks.

"How about a “duty” NOT to “migrate” if they have no LEGAL right to “migrate” where they are migrating to."

I suspect that's covered by "respect the laws" of the host country (i.e. you can not enter a country illegally and show respect for its laws).
