Hi letina, Vansask,
Yes, I am actually working in Singapore. As Singapore Police Force no longer issue Police Certificates to foreigners (I'm from Manila, Philippines), my alternative is to make a Statutory Declaration at a qualified legal practitioner or from the Commissioner of Oaths. I am still looking into this to make sure I get everything correctly. On top of this, I still need to obtain a police cert from my home country. Getting all these certificates is quite troublesome but I hope to be able to do it as soon as possible.
Best of luck to your applications! I'm sure they will be moving soon as well.
