A passport office was opened at Joo Chiat Complex in 1984. This office issued both international and restricted passports and was closed in 1999. The Immigration Department moved its head office to the Pidemco Centre in June 1986. Immigration officers were also deployed to places such as India and Hong Kong to open consulates and high commissions. All passports issued by Singapore immigration after 1990 were computerised and machine-readable. The Entry and Exit Control Integrated System implemented in the early 1990s was a computerized immigration system that was used at checkpoints to speed up the processing of travellers. A hotline for information was set up in 1992, with restricted access to countries lifted.
