Even i am on GTS applied in early May, no update yet regarding passport request letter. I received the biometrics correspondence letter very next day (14th), gave biometrics on 13th.Congratulations!! This is great news. Wish you and your family the very best. Can you confirm if you applied via the GTS stream? I applied on the 20th of March, gave biometrics on 15th July and received biometrics correspondence on 22nd July. No updates after that
