When applying for a family immigration visa, several key documents are typically required. These include proof of the relationship, such as marriage or birth certificates, and the sponsor’s proof of citizenship or permanent residency. Applicants must also provide police certificates, medical exam results, and evidence of financial support from the sponsor. Recent passport-sized photos, completed application forms, and proof of payment of immigration fees are also necessary. Depending on the case, additional documents like adoption papers, divorce decrees, or legal name change certificates may be required. It’s essential to verify the specific document requirements for the country you’re applying to and ensure all documents are complete and accurate.
