I know this guy he is 19 and illegal in uk can he aplay for asylum he was 16 when he came here?

Question

he is originally from south asia

Answer 1

He will most probably be sent back to South Asia if he dose not have a good enough reason to be in the UK. He should have applied when he was 16 and under age because now that he is 19, he is not considered as the Uk's responsibility therefore has a possibility of being sent back.
