Each visa holder receives a non-immigrant number, which validates his stay in the United States. The non-immigrant visa number shows up in red ink on the lower-right side of the non-immigrant visa. Do not confuse this number with the control number at the top of the visa. USCIS verifies visa authenticity by keeping a database of all visa numbers and visa holders associated with them. In most cases, a non-immigrant visa number serves no functional purpose for a visa holder.
