No, not really. Packet 3 was delivered to the consulate on 15th September and we hadn’t heard anything from them, so we emailed them today asking if all is good and if we can go ahead and schedule the interview, to which they officially replied and said we can go ahead with scheduling the interview.
My suggestion is just not to wait too long for them to contact you, but maybe if it’s been over 7-8 days since packet 3 was delivered to them, you can email them and ask. If they replied within 6 minutes to our email, that
means they had already gone through our documents and there were no issues but they simply hadn’t emailed us about it yet.
