Singapore Certificate of Identity
The Singaporean Certificate of Identity is an international travel document issued by the Immigration and Checkpoints Authority to Singaporean permanent residents who are stateless. Use. A holder of a Certificate of Identity can enter Germany and Hungary visa-free for a maximum of 90 days within a 180-day period. In the case of Germany, for holders of a COI to enter visa-free, their travel document must be endorsed and issued under the terms of the Convention relating to the Status of Stateless Persons of 28 September 1954. However, as Singapore is not a signatory  to the 1954 Stateless Persons Convention, in practice the visa exemption to Germany does not apply to any holder of the COI. However, COI holders can nonetheless qualify for a visa exemption to Hungary since the Hungarian government does not require their travel document to be issued under the terms of the 1954 Stateless Persons Convention.
