I believe the answer is:

brain drain

I'm a little stuck... Click here to teach me more about this clue!

'intelligent emigres finding' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?

'undergarment in sewer?' is the wordplay.
'undergarment' becomes 'bra' (bra is a kind of undergarment).
'sewer?' becomes 'drain' (drain can mean a sewer).
'bra'+'in'+'drain'='BRAIN DRAIN'

Can you help me to learn more?

(Other definitions for brain drain that I've seen before include "Emigration of talent" , "Emigration of highly-skilled people" , "Movement of highly skilled people" , "Haemorrhaging of talent" , "Loss of talented people" .)
