Absent Asians set out for Spanish city (3,9)

Ross

I believe the answer is:

san sebastian

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

'for spanish city' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'absent asians set' is the wordplay.
'set' is an anagram indicator (instruction to set the letters).
'absent'+'asians'='absentasians'
'absentasians' is an anagram of 'SAN SEBASTIAN'.

'out' is the link.

Can you help me to learn more?

(Another definition for san sebastian that I've seen is " Port".)
