Does a passport come with a visa?

No. First you get a passport and then - if required - you apply for a visa. A passport is an identification document. A visa is permission to enter a particular country for a particular reason and for a specific time period. {There are different types of visas for tourism, work, accedemics, Embassy/Government business, etc., and different lengths of stay for each type of visa. Every country has its own rules for issuing a visa.}
