Are you interested in immigrating to any country or want to sponsor someone? Many countries provide for immigrant visas based on family ties, employment, adoption, special immigrant categories, and the diversity visa.
In general, a person who wishes to immigrate to any country, they must have a petition approved by that country Citizenship and immigration service before applying for an immigrant visa. The petition is filed either by a qualified relative or a potential employer. An individual with an approved petition and a priority date that is current for processing (when applicable) is eligible to apply for an immigrant visa or K nonimmigrant visa.
