India Post — Foreign regd post stuck at chennai airport

I booked a Document to NJ, USA at Shenoy Nagar PO on 10.4.2021 vide AWB No RT[protected]IN. on tracking I find this item was BAGGED at Chennai Airport Sorting Office on 12.04.2021. Since then almost 15 days have passed but there is no movement atall. When is it likely to move and reach the destination ?
