thank younoticemesenpai said:MPNP has this EE sub stream. Ideally and according to MPNP, if you are already a nominated applicant, you should not apply for EE unless you are advised to do so. If you are not yet a nominated applicant, then you can. You will only have a problem with your EE profile if you claim that you are a provincial nominee if you are really not one.
You don't need one but it may increase the points you receive on the CRS and improve you chances of being invited to apply.
