first of all, thanks 4 your fast reply!
Ok, noted the limit is 6 months: we had than received a wrong information when left Italy.
This makes possible fro us simply ask help of Lalli Singh for the parking, coem back in Dec. and finish the second part of our trip within the 6 months term.
For other users: option to exit to Nepal or Pakistan and re-enter it seesm not to work as, if the veichle re-enter before six months, it seems second stay is added to the first one and total lenght of time still does not have to be over 6 month.
Enterin India on 1st. January, leaving 31st. March (90 days in India), exing to Nepal, re-enter before 1st. October (180 days form 31st March): in this case, for second stay only other 90 days will be allowed.
Ex.2: As per above, back coming back to India after 1st. October: than veichle can stay in India for another 180 days.
Hope this India long stay veichle thread will be helpfull for other mates!
