For Indian citizens planning a trip to Saudi Arabia, a visa is indeed required, with options ranging from tourist and business to work visas, offering flexibility for various purposes, and allowing for a maximum stay of 90 days. Given the significant cultural differences and the importance of adhering to local customs, especially during the holy month of Ramadan, familiarizing yourself with Arabic greetings will greatly enhance your interactions, as English is not widely spoken outside major tourist areas. Flights from major Indian hubs to Riyadh or Jeddah are frequent and typically take around 4-5 hours, but remember to account for the 2.5-hour time difference and potential currency exchange for the Saudi Riyal.
