What are the visa & residency requirements in Nebraska?

"The process of applying for a visa in Nebraska involves submitting a valid United States passport, documentation showing the purpose of the trip, a completed visa application, and a fee. Depending on the type of visa being requested, additional documents may be required. To apply for residency in Nebraska, applicants should apply for a permanent residency (Green Card/immigrant visa). Applicants must either file Form I-485, Application to Register Permanent Residence or Adjust Status, or seek an immigrant visa from the U.S. Embassy in their country. Application materials include a completed form, biometrics, supporting documents, and a fee. After the application is approved and the associated fee is paid, an Immigration Judge will interview the applicant to evaluate their eligibility and grant lawful permanent residence," remarked another expat who made the move to Nebraska.
