I plan to get married by the end of 2020 and move to Montreal, what's the easiest way to get the PR certificate? Heard my options are trough Arrima and EE. Can I apply for my future spouse before getting effectively maried?
Do not immigrate to Quebec. If you have been living under a shell, just google about what Quebec's immigration department is doing to CSQ applicants. They rejected 18,000 applications in the blink of an eye.
Do not waste your time or money to immigrate to Quebec. Quebec is a province ruled by a bunch of racist xenophobes.
Also do not believe your lawyer or immigration agent whatever they say about Quebec. They might say you will get invitation in Arrima portal if you apply now etc. They just need your money. Do not trust your lawyer or immigration agent or even the Quebec immigration department to do anything right.
Follow the advice that many have replied to your question. GO FOR EXPRESS ENTRY and other provincial nomination programs.
