The Department of Migration is now photographing US citizens who enter the DR with birth certificates and photo IDs. The plan has been adopted to reduce the number of illegal aliens who use these documents to later gain illegal entry to the United States. The measure does not affect US citizens who travel using their passports. The computerized systems are in place at each of the international air and maritime ports. Miguel Vasquez Escoto said that the scheme will use the birth certificates primarily of minors entering the country’s parameters. The start of this new system coincides with the start of the new US Department of Homeland Security US-VISIT program (United States Visitor and Immigrant Status Indicator Technology) in place at US airports and seaports as of 31 December 2003. Scanning equipment is being used to collect fingerprints and digital photographs of the visa-holding visitors to ensure compliance with visa and immigration policies.
