So you want to fly in India.
It works like this:
Once you have successfully negotiated the terms and conditions with the company of your choice, that company will send you a letter of appointment, which you sign and mail back.
It is like a working contract.
Keep in mind, you need 100 hours on type to fly commercially in India.
You have to provide your employer with the following:
Copy of your passport
Copy of your license
Copy of your medical
Copy of your loogbook showing the last check ride on the desired type signed by the TRE, less than six months old. It doesn't hurt to also mail the check ride protocol.
Copy of your radio license
Letter of verification from your license issuing authority. Can be obtained online with the FAA, JAA countries want to be called up,
afaik.
6 photographs
With this the company will get your license validated by the Indian DGCA and get a security clearance.
This process will take 2 month+, don't be impatient.
After they tell you that everything is in order on their side you take a copy of the letter of appointment, walk up to the consulate/embassy and get an employment visa glued into your passport. Make it valid for a year with multiple entries.
The application form can be downloaded from the government web site.
You'll need 2 photographs again and pay 80 Euros. The company will reimburse you.
Now it is time to go.
Your employer will either provide you with an airline ticket or you buy it and get reimbursed in India.
Once you have arrived a company official will take you to the DGCA to get your license validation certificate.
You have to show up in person and present your original documents/logbook.
They might get you involved into a little chat to see whether you speak english...
Shouldn't take more than ten minutes, after an hour or two of waiting, that is.
After seeing the DGCA you have to go to the foreigner's registration office and pick up your permission to stay in the country. You need 4 photos here and about 3 to 4 hours time.
Now since you have taken that hurdle you are good to fly.
Within the next 90 days you have to pass an air law exam, so sit down and study a bit.
Bring a lot of photographs with you because everything you want to get going here needs at least one picture. Scanned and printed on photo paper is fine also for the above.
Setting up a bank account- 2 photos
Getting a SIM card- 2 photos
Mobile Internet Access- 2 photos
Etc.
Have fun!
