Re: When compare it with India
if you have a tourist visa valid for more than 6 months and you intend to stay for more than 4 months, you must report arrival and departure to the LIU [Local Intelligence Unit] in your city.
it’s a a very easy process. my folks do it all the time…you just have to make a trip to the LIU and the rest is taken care of…you just have to bring two passport size pictures.
