The answer to this question depends on which country you are asking about. Each country has its immigration laws, so it is impossible to give a simple answer. In general, though, most countries have national-level immigration laws, with some leeway for individual states or provinces to set their own rules within certain limits. For example, in the United States, the federal government sets the overall policy for immigration, but states have some discretion in enforcing it. So, while the primary law governing immigration may be at the federal level, there can be considerable variation in how it is applied at the state level.
