My friend just applied recently, she submitted her diploma and transcript of records from the Philippines, (without a letter saying English is the medium of instruction) not from top universities in the Philippines, and English is one of the 2 official languages in the Phils.
And she also submitted the CLBPT, we argued about that CLBPT as not acceptable and only CELPIP or IELTS is accepted. I said to her you can always try if the officer is strict, it will be returned lol.
CIC accepted her diploma and TOR.
