Obtaining residency in the United States is a process that requires meeting certain fundamental requirements. Among the most common requirements are having a family member who is a citizen or permanent resident in the United States who can sponsor the application, having a valid job offer in the country, being a beneficiary of an investment visa, or requesting asylum or refuge. In addition to these basic requirements, it is necessary to present a series of documents, such as proof of identity, criminal record and proof of family or employment relationships. It is important to take advice from specialized immigration services to ensure you meet all the requirements and submit a solid application.
