Staying in Singapore beyond your allowed visit visa period is a grave matter that may lead to monetary penalties, detention, or a ban on re-entry. The severity of the penalties will depend on the length of the overstay. Brief overstays could result in fines, but extended or repeated violations might carry stricter repercussions. Immigration takes visa compliance seriously, and visitors should leave the country before their Short-Term Visit Pass expires. If more time is needed, visitors should seek an extension from ICA before their current visa runs out.
