There is a very good chance that all incoming questions about how to know the status of a UK visa application can be marked as a duplicate as soon as it is posted. If you see a new (UK) question about this, please close vote it as a duplicate of How to track my UK Visa Application Status?
There are 11 questions in the archives with the application-status tag and about 7 of them are UK, hence duplicates.
So should I go through them and initiate a close vote on them?
If so, I would be close voting questions that were posted in the past, is it OK?
If I'm close voting an old question, should I leave a comment about it?
Normally I like to comment on NEW questions when I close vote something (on advice from my TSE guru, Mark), you probably have seen some of them.
But does it make sense if the OP is long gone?
