ah, ok, there are already various stickers that permit this, most of them have |lang=fr added in, like {{French Roots|lang=fr}}
This would not necessarily work with this, since depending on the countries, the nomenclature varies. Migré de France au Canada / Migré de France en Allemagne ....
Possibly it should be set to be manually entered text, such as some of the occupation stickers, like {{Religion|image=ADWP-602.png|text=was a Nun.}} which can be amended in the text part, the image remaining the same.
