OK. If Immigrants to Texas is the correct category, then which category applies for Immigrants to Georgia? If it refers to the US State of Georgia, it would have to be Immigrants to Georgia, United States. Otherwise you will get immigrants to Tbilisi and Atlanta filed in the same category. Comments!!
If you are going to include towns or cities, I know plenty right in Maine that could cause mass confusion.
China, Poland, Peru, Norway, Mexico, Egypt, etc etc etc.
Ambiguation has already been discussed with the Categorization Project. For Georgia, it was decided that the country would be listed as [[Category: Emigrants from Georgia (country)]] and [[Category:Immigrants to Georgia (country)]].
In regards to Malcolm's comments re: Venice and Ontario, there are currently no plans for the Migration categories to drill down to the city level - so the these are a non-issue.
