Form 2555 and supporting document

Hello,

 

I will have to print out my jointed tax return and form 2555 (Foreign Earned Income Exclusion, as my wife works in Hong Kong) and visit local IRS office because I also have to do first time application of the ITIN with form W-7.

 

I wonder do I need to provide any supporting document for Foreign Earned Income Exclusion application?

 

From here: https://ttlc.intuit.com/community/tax-credits-deductions/discussion/do-i-need-to-send-any-documents-...

It mentioned e-filing does not need any supporting document, but I am doing a print-out.

 

Best,

Jake
