The reply to your question in brief is: your state should be similar to that of the [Muslim] inhabitants of where you are. So, if they were still observing fasting then you should observe fasting with them even if that means you would be fasting for more than 30 days [the max. number of days, normally observed in the month of Ramadaan]. This is the opinion of Shaikh Abdul-Azeez Ibn Baaz.
