The Problem: Migration Traffic to Expatriates
Adding a migration target to Expatiates isn't currently an available option since SE doesn't add migration paths to sites in beta:
Migration path between Travel and Expatriates
Why aren't questions that belong on Expats migrated there rather than closed?
When should we consider adding a default migration path?
In addition, most of the traffic on Expatiates comes from migrated questions, which in itself could be an indicator of an unhealthy beta.
The Solution: Guiding Users To Expatiates
One possible solution to this problem could be adding a brief sentence on our ask page pointing askers to Expats. Our ask page currently looks like this:
Something like
If your question is about immigration or moving for extended periods of time, ask it on Expatriates instead.
