AINP Strategic Recruitment Stream- Engineering Occupations Category?

[Maruchan]

Hello,
I have a question regarding AINP Strategic Recruitment Stream- Engineering Occupations Category.
1- Do I need a job offer to apply for AINP Strategic Recruitment Stream- Engineering Occupations Category?(I got a lot of ambiguous answers from other websites). If no, I see that there is a requirement for job offer letter from current employer in the checklist. What should I submit in this case?
2- Is it required that I stay in Alberta to apply for AINP Strategic Recruitment Stream- Engineering Occupations Category?

Thanks in advance.
