No. You have the right to appeal if you choose to do so.If I apply for appeal. Can it create problem in future applications? like if i go with CEC in future then.
Having said that, the costs of an appeal (with the help of a lawyer) could be high and if you are still in the same position with your employer...it may be better (financially) to simply reapply, assuming you have maintained your legal status and authorization to work in Canada.
