Immigration officers in ICA are divided generally into Junior Officers and Senior Officers. Under the current Home Affairs Services (HAS) (ICA) Unified scheme, new junior officers and senior officers join as Direct-Entry Sergeants and Direct-Entry Inspectors respectively. Direct-Entry Sergeants range from ITE graduates to polytechnic diploma holders. Direct-Entry Inspectors must be graduates from a university accredited by its home country. New Sergeants will become Primary Screening Officers, while Inspectors will become Team Leaders in their foundation posting. Regardless, all new officers will be posted to Tuas, Woodlands or Coastal Command.
