Indian citizens can obtain an e-visa for Iran, allowing for a maximum stay of 30 days, with applications typically processed within 3-5 business days for a fee of approximately $75 USD. Given that Iran operates on Iran Standard Time (IRST), which is 2.5 hours ahead of Indian Standard Time, plan your travel schedule accordingly, as this time difference can impact immediate arrival plans. While popular flight routes connect major Indian cities to Tehran, be aware that the cultural nuances and reliance on Persian language for many transactions mean having a translation app handy could greatly enhance your experience, especially outside the main tourist hubs.
