A visitor's entry into Singapore is neither a right nor automatic and each entry is considered on its own merits. The grant of Visit Passes to visitors is assessed and determined by the Immigration & Checkpoints Authority (ICA) officers at the Singapore checkpoints upon their arrival. Visitors must fulfil the prevailing entry requirements and may be subjected to interviews and additional checks before they can be considered for entry. Those who are ineligible for a Visit Pass will be refused entry.
