Thanks a lot Skywalker_RT for your quick response, appreciated it.
I have been living in BC for 4.5 years and have a valid WP until Mar-2017.
That might be a problem. It's hard for them to believe that you're gonna settle in NB when you're living in BC for so long.
Could you please confirm following things for me. So that I can easily understand about NBPNP programme.
1) How many PNP categories are there under NBPNP and Where I can check the eligibility criteria for them
This page I shared is from the Express Entry stream. There are other categories, but they are for entrepreneurs or require family/employer support. For the EE stream, you just need to read that link thoroughly. It's pretty clear there. The biggest problem is that there aren't information sessions in Canada, only overseas.
2) How can I nominate for them
First, you have to send an expression of interest, provided that you satisfy one of the categories on the link. Then, if they're interested in you, they will send an invitation to apply, after which you have to send a complete application.
3) High level steps to be nominated for them
Answered in number 2.
4) Fee details
250 CAD.
5) Processing timings
Usually 2 months to get ITA after sending EOI (if you qualify) and another 2 months after your application is received.
6) Shall I apply for multiple PNP, let's say SINP,OINPAPNP,...
You can, but since you're living in BC for a long time, you should focus on their PNP. Other provinces might not be convinced that you wouldn't stay in BC after getting the PR, as there's nothing they can do to prevent you from doing it after your PR is confirmed.
I look forward to hearing from you on above points
thanks again for your support and help.
