Hey girzim,
if you are still putting together the application, good luck with that! Just a tip about proving to go to Canada ( my partner and I are also living in a different country, not Canada and not mine, so it was also just a choice for Canada... but difficult to explain!) - we got approved, and he didn't have a job offer etc. What we did is we wrote a timeline of the steps that we intend to take in order to move, and also got letters from his family saying that they will support us when we arrive...
For the timeline, we got quite specific - try to include the steps that are needed in Korea to leave the country, how long in advance you need to cancel your rent agreement etc. Pick a date ( even if you are not completely sure for now) of when you want to land in Canada, and work your schedule"backwards" from there. You can also get some quotes (over the internet) from moving companies, to show that you have looked into the practical aspects of things. You could also buy a fully refundable one way plane ticket, print it, and include it in your application ( and then cancel it later on if you don't intend to use it). If you don't have a job offer to go back to, you need to build your case to show that you will be moving to Canada once your PR is approved, and that you are aware of what it means in terms of practical aspects...
Hope it helps!
Cheers,
Sweden
