By regular post. And I am so surprised the date of the letter is March 8, 2011, which is received just today. We did our medicals in mid of February only. The letter says that the application has reached the final stage and that the permanent resident visas for me and my family are now ready for issuance. They asked us too to submit recent photos and to fill up the "Updated information Chart". Amazingly fast..It was my LMO which i think speeded up the process from the medical request onwards..It was deeply asleep before the LMO was submitted.
