Help a brother out!

I am moving to Ireland on a CSEP (Critical skills visa) and my plan is to get my Stamp 4 after being there for 2 years.

Stamp 4 can be after 2 years and then when I get my Stamp 4, I plan to bring my wife over on a dependent visa.

Now our boss says that my current visa application will be rejected on the basis of my plans to bring my wife over after 2 years, and also says that in 2 years, rules will be changed re immigration wherein the automatic Stamp 4 eligibility will not be allowed and bringing a dependent will also not be allowed
