The 300 visa application was submitted for the epidemic visa, and the processing of the 300 visa was suspended due to the epidemic. After consulting us, we quickly settled on a plan. First help the guarantor to apply for an exemption from leaving Australia, and after the exemption is approved, go back to China to register marriage with Mr. Y. After getting the marriage certificate, we immediately updated it to the Immigration Bureau, and the 300 visa was successfully converted into a 309 visa without re-payment, and the trial continued. After about half a year of waiting, Mr. Y's 309 visa was successfully approved. Our experience helped Mr. Y realize his wish for a husband and wife reunion early.
