India is one of the most vibrant, colorful, exciting places to visit in the world. The diversity of people, culture and cuisine make it a worthwhile destination for any traveler. Here are nine tips to ensure your next (or first) trip to India goes as smoothly as possible.

1. Print your visa. No, the other visa.

A double-entry tourist visa to India, with a four-month window to make your first entry, is fairly easy to obtain through a website run by the Indian government. However, when you receive the confirmation email that your visa has been approved, there’s some confusion as to what you actually need to print out and present to the authorities.

As it turns out, you aren’t actually emailed the document you’ll need to print out in order to enter the country — and to board the plane to India. At least 10 people on my flight to New Delhi were pulled out of line during boarding and hustled to a small side office at Newark Liberty International Airport to print out the proper Electronic Travel Authorization form needed to enter India. They had a printout of the email confirming their visa — that is not what you need.

I happened to have a printout of the proper document, but I found it purely by chance. When you’ve been approved, go back to the visa application site and click “visa status.” After entering your information, click “print status” at the bottom of the screen, and the proper form should start to download. It should have your photo and a bar code on it — if it doesn’t, it’s not the right document.
