Don't worry. I am with you in the same boat. Applied just for my mom. Submitted application in Dec2022, more/same documents requested in Mar and Jul. Not even Sponsorship approval yetI am glad some of our 2022 applications are going so fast. From submitting documents to request passport it only took eight months. Wow! I am the one with one parent stuck in medical check, it may delay me at least four months for another medical check in my case. I am still happy with those applicants got approved. Hope my parents will go through everything smoothly too!
