Another point to keep in mind is that by giving out your personal data, at least one other person, if not a whole company, may know your data, with many small and large gaps.
It is also important to note that almost none of the European incorporation agencies are directly linked to the registry for the incorporation of an offshore company, or do not register your offshore company directly there for you.
Thus, there are further possibilities that your data is insecure, possibly develop into Panama Papers. A risk that you should avoid at all costs.
Another small obstacle is not only the transfer of your data, but also the time, because it is much more effort, because several companies, founding agencies or employees are busy with the foundation. Not to forget also that here fast times with a misfortune, something is communicated wrongly and/or not correctly.
We all know the game "Chinese whispers", where something is said at the beginning and the last in the chain names the result, which usually says something completely different than the origin.
And when we are on the subject of correction or possibly an extra request, you must also bear in mind that this takes much more time than if you set up directly with a Seychelles incorporation agency.
