the writer will most likely have a network of contacts, located within a specific field, that can help him completely address the intricate requirements of any paper
Really? Are you suggesting that this "network" can't be contacted via online channels?
Anyway, if the writer can't address those "intricate requirements" without consulting a network of contacts, then they should probably drop professional academic writing and pursue other interests.
My point is that being exposed to the correct elements that can help a writer from India address the academic paper requirements of a British or US student.
Is this a complete sentence?
While they may not be in the country required for the completion of the paper
Rarely does an academic writing assignment really
require the writer to actually be in a specific country. Please understand that.
claim these qualifications
Being in a country is NOT a qualification.
