That is incorrect. Most Indian spousal sponsorships take around 12 months. Not sure about Chinese.I support this theory, just go check the spousal sponsorship timelines, applicants from India / China get here within 6 months (or less) and other countries can easily go the full 12 months or even more
Oh my application was received the first possible day (April 26th) and it is still on "application received" so consider yourself luckier than most people
