The green card approval process can be long, sometimes up to 12 years. Even extremely well-qualified applicants are met with lengthy wait times. This is why it is crucial each step is properly executed by the applicant and/or their sponsor. If the applicant remains in lawful status, has chosen the best pathway, meets the requirements, has submitted complete and accurate documents, and has provided enough supporting evidence for his or her claim, they should be able to switch their visa for a green card.
