I need an advise from you all. If i apply through express entry with my spouse I can maximum claim points to 415 whereas if I apply alone without my husband the points rise to 429. I have some queries:
a. Is it possible ? I mean applying for express entry and not taking your husband along with you ?
Yes, it is an option.
b. If yes, then after how long do I need to wait to invite my husband to Canada if i land there.
I don't remember right now, I think 18 months (please confirm). But, on a personal level, I really wouldn't recommend separating your family.
If it was me, and I was the primary applicant, I'd do everything in my power to improve my IELTS score, learn another language, or even making a Master's Degree (one that could be done in 1 year preferably) to increase my CRS as a family.
