The I-485 form is used to apply for lawful permanent resident status in the United States. Immigrants may be eligible to apply for the status through a job offer, through being granted asylee or refugee status, or because they have a spouse or family member who is a U.S. citizen or lawful permanent resident.

The filing fee for this form varies by age and eligibility category, but varies from $0 for those having been admitted to the United States as a refugee to $1,225 for individuals ages 14-78. Applicants must provide sufficient evidence to have their petition granted. Specific evidence varies by the eligibility category under which the individual is applying, but may include evidence of a family relation, proof of immigrant category, or a confirmation of a job offer, among other documentation.
