welcome to rootschat>
click on link and it may give some ideas on how to do material for Singapore>
https://familysearch.org/learn/wiki/en/Family_History_Records_at_the_National_Library_of_SingaporeGenerally after about 1885 civil registry for British Subjects born in the Commonwealth are available on microfische at larger genealogical societies, some large libraries and WRO offices throughout the United Kingdom. Partial lists of those same microfische appear on Findmy Past.... check the free index search engine first if u dont have sub.......... the entry of birth or death or marriage will be somewhat similiar to those appearing on freebmduk so copy the "cat number" area of the listing precisely, then you can order the documentation from WRO in UK.
War files ex Singapore.......if British then check the index of National Archives [UK] and there may be a listing of the file.... if it survived. There are returned servicemen leagues for folk affected by Japanese Occupational Forces.......

I strongly suggest you contact the Singapore Library in the link by mail NOT email.
I would also be asking for an address for archival materials regarding immigration to the USA/ Canada. I would also venture your reasearch into Australia at that time as some refugee vessels made it to the northern border ports of Australia........... check NAtional Library of Australia, also check Trove, Australian National Archives, and on the back of ancestry.com are "Ships Lists" .... to access them quickly enter your folk names + Ships Lists into google.........
hopefully in all that you may get lucky and find some material
good luck
