Hi all,
Actually those who have something really big to share with LVO voluntarily then they should do it, otherwise refrain from any thing else.
If you visit you spouse in Pakistan, or you have a new baby etc. this kind of major things help in the case strength.
other than these do not send anything like communication proof, financial assistance, new gifts receipts or birthday pics etc, wait for a request from Visa Officer.
when visa officer finish review of your document they update the status regarding your application in their server internally. after that if they need more documents they will ask. otherwise they will forward it for the next check or stage.
If you send new documents, then the status update will be postponed until newly arrived documents get a review from visa officer to update the status.
