Let's shed some light on this particular issue.
To be an regsitered agent / firm at SIBA they pay 5000 USD in government fees have a local director and 1 staff minum in an office on the beach somewhere or in the slams of the Seychelles. You get monitored by their strict rules all the time, you will have to follow strict documentation compliancy and at the end of the day it makes the whole thing very complicated. Actually you don't even know if the director or this extra staff is aware of to be an director / staff in this particular company.
Frankly let me ask you, where do you see more flexibility and what let you think that the licensed agent is more reliable and will be there tomorrow compared to the other two?
For me, as long as my privacy/anonymity is respected, I don't care if the incorporator is registered or not at SIBA and as I understood a "not registered" agent offers much more privacy than a registered one.
What would happen if the agent disappear, the company has to find a new agent?
