Regarding state borders, under minarchism, the state retains the function of protecting borders from armed invasion, as well as negotiating with other states regarding where these borders actually lie. Therefore, if foreign armies are viewed as a type of migrant, their presence on the state’s territory will be determined by intergovernmental agreements, which, in turn, will be based on the opinion of those who hired that government. In a democratic minarchist state, this will be the democratic majority.

As for all other migrants, the regulation of their movements does not fall within the state’s sphere of competence at all. How many labor migrants, tourists, or refugees to let into a minarchist state is decided by the owners of the infrastructure used for their movement. How many to let across the threshold of an establishment is decided by the owner of the establishment. How many to hire is decided by the employer. And so on.
