Bangkok , Thailand ( CNN ) -- Thailand has revoked the visa of a Russian pianist accused of raping a 14-year-old boy , an immigration official said Thursday . Thailand 's immigration bureau revoked the visa of Mikhail Pletnev because it believes he poses threats to the country , according to Maj. Gen. Pansak Kasemsan . The development means that even if the charges against Pletnev are eventually dropped , he will be deported from the country . Although the revocation of the visa is already in place , an exception allows him to enter the country while his case is pending . Pletnev was arrested and charged July 6 with raping the teenage boy in the Thai beach town of Pattaya , where he owns a house . The crime carries a maximum prison term of 20 years . The judge released him on a $ 9,000 bail until the criminal charges against him are resolved , with the provision that he return to the seaside town of Pattaya every 12 days to renew the conditions of the bail . That means Pletnev can travel abroad as long as he continues to make his court dates . Pletnev was in Thailand on Monday and is due back in the country on July 30 . His attorney said he left the country Wednesday to see his mother for her 89th birthday . Thailand remains a destination for child migrants , many of whom enter the sex tourism industry , according to the Child Protection and Development Center . `` Pattaya in particular has developed an international reputation for child sex tourism , '' the nongovernmental organization says on its website about the town two hours south of Bangkok . `` Anti-trafficking researchers targeting street children estimate that Pattaya hosts about 1,500 to 2,000 homeless and impoverished children per year , while numbers are increasing . Children search for work , migrating -- alone or with their families -- from Thailand 's northeast provinces , Cambodia , Burma , Laos and Vietnam . '' CNN 's Kocha Olarn contributed to this report .
