Every visa question should include citizenship (if you want to be persnickety then the passport issuer country) but almost noone does that. Is it possible to add a hint about this somehow?
You are suggesting to modify the
Ask a Question tooltip which appears on the right of a "new question" form. As far as I can see from SO and TSE, that part doesn't seem to be customisable, aside from changing the
Is your question about xyz to make
xyz reflect the nature of the SE site at hand:
It's the help centre is that is customised by sites on-demand. I don't know if modifying the
Ask a Q section as you suggest would be a good idea though as it would somewhat become a blazing statement that all we talk about on TSE are visas. Yes you guessed right,
*visa* questions are in my ignore-list.
I would rather add the information in the help centre. The more informative the help section the better. However don't expect to get very high returns from this as visa-question users rarely read it anyway.
I have edited the visas tag wiki, hopefully that will catch a few of them.
No, we should not do this.
Overusing citizenship will basically turn it into a meta-tag, and those are not permitted on any Stack Exchange site. Plus, there are other tags with -citizens in them and we will have to add another tag.
