If you leave for good the country as we will on Saturday, the exit visa procedure has to be followed. There is not too many documents, which have to be collected the only interesting thing again is, that nobody really knows what is required. Let me therefore summarize here, what is required to exit India from a legally acceptable perspective.
First of all a Non Objection Certificate from the Tax Authorities is required, which states that you have been a good tax payer in India. With this NOC plus a letter from your employer, that your time is over, you need to go for an appointment to the Foreign Registration Office (FRRO) with these documents plus your passport. Once there they will tell you, that they will send a letter to the airport authorities anticipating, that you leave the country.
At the time the last exit on the basis of the residence permit you have to just hand over your residence permit to the officer at the immigration counter. This piece of information we still have to verify, because it will only happen next week, but I am sure, they let us go one way or another.

We have safely reached our next destination. The exit was not spectacular at all. I just mentioned to the immigration officer at the usual airport counters, that I am now leaving for good the country and we don't need our visas anymore. The only thing he did was collecting all the visas we gave to him and put more stamps than usual into our passports. The later could just be my imagination :)
