thank you very muchThey usually dont ask but they mentioned the landing form before the interview after the test, and also if you are not able to show any document than you might have to come again for interview. There was one person who didnt produce passports so they asked him to go back and bring passport in an hour or if not possible then they will send you another date for new interview only.
I brought everything including residential lease, tax returns, travel tickets, extra educational certificates, proof of English language classes, and CLB test. but they only checked 2 photo ids including PRcard, checked all passports, and asked to sign a page for declaration.
