Visa policies are regulations set by countries that determine who can enter, stay, or work within their borders. These policies play a critical role in shaping patterns of international migration by either facilitating or restricting movement based on factors like nationality, purpose of travel, and duration of stay. Additionally, visa policies significantly influence the flow of remittances and the dynamics of brain drain and brain gain, as they can either encourage skilled individuals to migrate or deter them from seeking opportunities abroad.
