Hmmm, you should be getting updates, it's not due to the country you are in.
Your best bet is to back up your sd card and any settings you want to keep, and then install the latest RUU, which should be 4.06.1540.2. The RUU will restore all settings to stock.
If you can't find that, an earlier RUU should allow updates too. The RUU can be run in Windows, just follow the on screen instructions.
