Individuals who want to enter and live permanently in the United States may apply for immigrant visas through the U.S. Department of State. After a petition is approved by the United States Citizenship and Immigration Services (USCIS), consular processing begins when filing fees, the immigrant visa application, and supporting documentation are sent to the National Visa Center. Afterwards, an interview is scheduled at the U.S. Consulate.
Criminal histories, previous immigration violations, gang-affiliated tattoos, and evidence of drug usage and alcoholism can delay or lead to denials of an immigrant visa application. There is no right to appeal of a denial of an immigrant visa application by law. However, in some instances, a waiver may be available to overcome a ground of inadmissibility (fraud or misrepresentation, criminal history, previous unlawful presence in the United States, deportation from the United States).
It is important that you are honest and forthcoming with your attorney, so that he or she can assess your case in the manner that a consular officer would process it.
