Got a call from a Canadian Immigration Agency, what will I do? UPDATE

Tweet

I created a profile in workabroad website and three days ago, I received a call from a Canadian Immigration Agency in my country. They're not offering a job for me in Canada but a chance to migrate in Canada. According to them, my current work experience is on the priority list of jobs in the said country and I'll be able to migrate there through the Federal Skilled Program - Express Entry. I am thrilled of course but now, I am doubtful. Pros: * Better life I think * A well-paid job * Country benefits * New environment Cons: * Very far from my country * Cold weather (but I think I'll get used to it in time) * Not sure if I'll pass the IELTS exam * I don't think I can gather the needed money for the "Show Money" policy something (if only salary deduction is available then that would be okay) UPDATE: My husband and I decided not to proceed in the processing of papers for immigration. I feel like I'm throwing away an opportunity however, I also think that it's the best for us.
