Yemen is on ICA’s list of places whose travel documents require a Singapore entry visa. The test ICA applies is the country that issued the document you will travel on. A passport issued by Yemen therefore needs an approved visa before you board, whether you are visiting relatives, seeing the city or attending a meeting.
Nationality, birthplace and residence do not change that test on their own. Someone born in Aden who now travels on another country’s passport is assessed under that country’s rules. A Yemeni citizen living in Riyadh or Kuala Lumpur who still travels on a Yemeni passport is assessed under the Yemen rules, whatever residence permit they hold.
ICA’s Yemen page names no exempt category. Diplomatic, official and service passports are not mentioned, so a holder of one of those documents should not assume an exemption and should ask ICA before travelling.
Some travellers also wonder how ICA will view a particular passport, for example one issued in unusual circumstances or by an office they are unsure about. ICA’s public Yemen page does not address this. Its general visa page invites travellers to contact ICA through its enquiry form, attaching a copy of the biodata page and the front cover, for assistance and verification. That is the reliable way to settle a document question; this guide does not attempt to answer it.
This page summarises ICA’s published requirements. It does not take applications or payments, and it cannot influence a decision. Visas and admission are decided by the Singapore authorities alone.
Begin with the parts that rely on someone else: the Form V39A signature and any official translations. Everything else can be prepared around them.
