I am preparing my documents for residency. When I contacted the state of Arizona for my state background check they told me that Arizona is a closed records state and that they do not provide background checks for visa applications. They said to use the FBI background check. My understanding is that I need both FBI and state background checks. The state agency said they will provide me a letter of denial stating that they do not provide such background checks. Does anyone know if that letter of denial along with the FBI background check will be sufficient?
