A:Answer To ASUS:
The "international warranty coverage country list" I found is in nowhere but the *VERY* U.S. ASUS warranty website for this unit:
https://rog.asus.com/us/laptops/rog-zephyrus/rog-zephyrus-m15-series/helpdesk_warranty/ .
If this unit does not have international warranty at all, that document should have no business of being there at all.
Well, unless you mean the M15 GU502 sold by BestBuy does not have international warranty, but they may have international warranty sold elsewhere.
