According to Marc and Claire Headley, two Scientologists who left the Church in 2005, residents at the base are not permitted to leave without the permission of a supervisor and have to work at least sixteen hours a day, from 8 am to past midnight, with shorter hours on Sundays and little time for socialising. Communications with the outside world are effectively cut off; cellphones and Internet access are generally banned, mail is censored and can only be sent via the internal mail system. Passports are kept in a locked filing cabinet.
