Work done at home source of concern for the USA, possibly (10)

I believe the answer is:

housecraft

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

'work done at home' is the definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'source of concern for the usa possibly' is the wordplay.
'source of' says to take the initial letters.
'possibly' indicates an anagram.
The first letter of 'concern' is 'c'.
'c'+'for'+'the'+'usa'='cfortheusa'
'cfortheusa' anagrammed gives 'HOUSECRAFT'.

Can you help me to learn more?
