So I guess my question is will the immigration officers go further than just looking at his record check? Would I be able to say that he has never been deported or anything of the sort before? Or do they check these things out in-depth?
If he does not admit that he was deported on the application, and
if the visa officer then finds out that he was, the application will probably be refused for misrepresentation, and he will be banned from Canada for 2 years. He could then reapply, but his credibility will be shot.
How much time they spend on the background checks varies. His Greek criminal record check came up clean, so they may not spend much time checking further. Still, his deportations are on record in Greece.
I would just be honest and admit the deportations.
