Visa - quotation

"Petitioner Samson Taiwo Dada, a native and citizen of Nigeria, came to the United States in April 1998 on a temporary nonimmigrant visa.  He overstayed it.  In 1999, petitioner alleges, he married an American citizen.  Petitioner's wife filed an I-130 Petition for Alien Relative on his behalf.  The necessary documentary evidence was not provided, however, and the petition was denied in February 2003."
