Sorry but @Fred did provide ample and easy claim. It is written at the bottom of your pink visa sticker, easy to inspect and understand.We seem to be going around in circles here, so this is going to my last message to you on this topic. There were already several officially declared exceptions to the 180 day rule (foreigner wife of an Emirati citizen, domestic helpers accompanying Emiratis having a scholarship for study abroad, etc.). These were exceptions which the UAE government had officially declared would apply EVEN IF those individuals' visa stamps had the 180 day rule written on it.
The UAE government, according to the gulftoday article, recently announced 5 additional official exceptions, one of which is the investor visa exception.
Therefore, IF the gulftoday article is correct, then it's no longer a case of non-enforcement of a rule - it's a situation where the rule itself has officially changed for investor visas EVEN IF their visas have the 180 day rule written on it.
So IS the gulftoday article correct? You claim that it isn't entirely correct but you've provided no evidence for your claim.
In the worst case, just do the visa again. Its anyway valid only for 2 years now (unless you have these new fancy onces), so you can fit some free time in between the renewals.
