Yes, if you're traveling to Dubai on **Air India**, an **OK to Board (OTB)** may be required, especially for Indian passport holders. However, since you have a **valid US visa** and are eligible for a **visa on arrival**, OTB might not be necessary. It's best to confirm directly with **Air India** as rules vary by airline. I’ve seen cases where services like **matrix** helped with OTB clarification and visa-related queries.
