Hi guys! 
I have some questions that I thought you guys could help me, especially if someone went through the same situation.
I am from South Korea and I came to Canada with an ETA (electronic travel authorization). According to the Canada government website, unless indicated on my passport, I may stay up to 6 months in Canada. My ETA isn't expired yet. And since immigration system has been changed to self-service kiosk, I haven't got any stamps on my passport.
I came to Canada to join my husband right after we got married. We applied for the Permanent Residence on Family Class - Sponsoring your spouse inland in December last year.
We also applied for open work permit (IMM 5710) at the same time but because of the bit of mistake package came back to us and we re-applied in May.
( I never worked in Canada since I came here)
We got through all the required PR process.
But I got this mail in September

This refers to your application for an Open Work Permit.
Qualifying foreign nationals who have submitted an application for permanent residence under the spouse or common-law partner in Canada (SCLPC) class may be issued an ope work permit until such time as you receive confirmation that your application for Permamnent Residence will be processed from within Canada. Your application for an open work permit will be considered at the same time as your application for permanent residence and if the letter is accepted, the open work permit will be issued to you.
--------------------------------------------------------
Now it's November and I've got mail that I am scheduled for the final PR interview with reserved time & date.
They want me to bring TEMPORARY RESIDENT DOCUMENTS issued by IRCC.
but I don't have work permits, study permits & visitor records.
My question is.. Do I have legal status now?
How can I get visitor records document and proof I have legal status?
I am worried about my interview goes wrong because of this situation. If so, we won't be able to apply at all. Once denied they would ask me to leave Canada and I don't want to go Back to South Korea and lose all this time we've been preparing all the forms and documents, paying the fees and also because they might not allow me to come back in the country.
Does anyone have any advise ? We have all set to send the application but I am not sure about applying to extend my status.
I appreciate in advance for any help!
Thanks!
