AMERICANS top the list of 176 foreign sex offenders who were barred entry into the country by the Bureau of Immigration (BI) airport officers during the first six months of the year. The foreigners were denied entry over their record as registered sex offenders (RSOs), or individuals convicted or wanted for sex crimes in their home countries. Immigration Commissioner Jaime Morente said a sex offense involves sexual conduct by the offender against a minor, or in some instances, sexual assault of a spouse. BI port operations chief Marc Red Mariñas said denied entry were 131 American RSOs; 19 Australians; 19 British; three New Zealanders; a Canadian; a Colombian; an Irish and a Guamanian. Mariñas added that foreign sex offenders who were turned back this year have already exceeded last year’s record of 136 intercepted RSOs.
