What are the visa & residency requirements in Kentucky?

"Visiting Kentucky requires the traveler to obtain a US visa, unless the traveler is a US citizen or is coming from a visa-exempt country. The application process for a visa involves submitting an online application, paying a fee and attending an in-person interview. Applicants for residency in Kentucky must provide proof of citizenship, identity, employment, and age. Depending on the type of residency, applicants may need to prove that they have lived in the state for some time prior to applying. The application process may also involve submitting tax forms, certain documents, and showing evidence of medical insurance. The Kentucky Department of Immigration and Resettlement provides detailed instructions on how to apply for particular types of residency," mentioned another expat when asked about moving to Kentucky.
