NRI return filing in ITR 1 AY 2017-18

As we know that, AADHAR is compulsory for filing of ITR. Alongwith it the PAN must be linked as the case may be, the application for updating aadhaar.

As one of my client who served in INDIA till september 2016, after that he went abroad & served the same company over there.

His earning in INDIA, amounts to 8 lacs approx, therefore employer had deducted approx 55000.

He, the client had taken home loan with HDFC, pure home loan for purchase of home. Interest of home loan is approx 221000₹.

Therefore, he, the client, with filing of itr is able to get refund of approx 35000₹.

But, as he does not own a AADHAR card, as he is now residing in NEW YORK.

He cant apply for the same there.

Give/ provide a solution for filing ITR 1 without AADHAAR.
