It is not easy. Most provincial nominated skilled worker programs need job offer, but companies need to get LMIA to hire foreign workers. So why companies bother to do so much work to hire foreigners. My age also affect my scores in the express entry system.
Maybe due to the fact when they apply for a TRV they probably need to declare family members whether all applying for a TRV or not or whether accompanying or not so as a spouse your name/DOB could be picked up there.
