Q: What if the current dignitaries have immigrant passports?

There has never been an immigrant passport, only an immigrant visa. Passport is a document issued by a country to citizens who want to go abroad. This person travels abroad, visits relatives, travels, works and studies abroad with passports. And no matter what he does abroad, his passport is the same. Then he wants to travel to a country, which gives him a tourist visa, wants to study in this country, gives him a visa to study abroad, wants to work in this country, gives him a work visa, wants to immigrate to this country and gives him an immigrant visa.
