Thank you for your reply,
I am inland applicant, I think that my VO in Sydney, NS. I haven't received a medical request yet.
I am able to covers all the cost for a new EE application, But it seems sound is not right to walk away from this PNP paper base which cost me around (1500 for Ontario nomination plus 2080 for federal PR).
According to current timeline I should be 7.5 month away from completing PR mystery !!
So if i accept the EE invitation I should save 1.5 months -- too costly for only 1.5 months.
Also, My current working permit has been bridged and going to expire again on June 2018. I am just thinking what if things goes wrong with paper base and the final decision passed June 2018, Can i get another working permit bridge ?
