The only channel there is. The site has no forms: it is static, and there is nowhere for a message to arrive.
If a figure is wrong
This is the most useful message anyone can send here. The data comes from open sources, some of it goes stale quietly, and that is easier to spot from outside than from within.
For a correction to be checkable and applicable, a message needs three things:
- the country and the section of the page, or better a link to it;
- what exactly is wrong — the value shown and the value it should be;
- a link to a source, preferably an official one: an agency website, the text of a law, a statistics office publication.
Without the third item a correction cannot be applied: the project's rule is never to fill a field with a guess, and swapping one unverified number for another breaks that rule just as surely. How a source is chosen, and what happens when sources disagree — on the page about the data.
What there is no point writing about
The project does not arrange visas, does not accompany a move and does not advise on an individual case. What is gathered here are public facts with links to their sources — they do not answer the question «will I personally be granted residence», and they cannot.
