As an Indian citizen, am I eligible for a 30 day visa exemption as I’ll be on route to US?

From herehttps://en.wikipedia.org/wiki/Visa_policy_of_South_Korea#30-day_visa_exemption:

Non visa-exempt nationals who are in transit through South Korea are visa-exempt for 30 days, provided they hold a physical visa or a residence permit issued by the following countries, and meet one of the routing requirements: • They are directly arriving in South Korea from one of these countries and going to a third country, or directly leaving South Korea to one of these countries after arriving from a third country; or, • They are arriving in South Korea from one of these countries and have transited in a fourth country for less than 72 hours before entering South Korea, and continuing to a third country; or, • They are leaving South Korea after arriving from a third country to one of these countries and will be transiting in a fourth country for less than 72 hours.[1]
