How many provinces are allowed to select while filling the application

[siva9584]

Dear All,

I am done with all steps except applying through express entry. I am a post graduate in CIVIL ENGINEERING. I have few doubts
1) Civil engineering comes under which field of study..........either science general or architectural or other?
2) How many provinces we can select? if only one then which one is the best for civil engineering?

Thanks in advance for your kind reply.
