Here, look. Presumably, all these people saw themselves as artists in Paris. Most likely, none of them had studied at the Paris Graduate School of Fine Arts (this can be verified, but isklyucheiiya should not be many), but no one protests the fact that they were called

First Paris School:

Picasso, Chagall, Modigliani, Paskin, Soutine, Flint, Hmelyuk, Kisling, Kikoin, Fujita, Kirshenbaum, Marevna, Mel-Mutter, Tereshkovich and many others.

Second School of Paris:

Polyakov, Lanskoy, de Stael, Seifert, Hartung, Heifer, Jan, Pelayo, Pierrakos, Prasinos, Seiler, Senes, Vieira da Silva, Zao Wu-Ki (there are also French, thank God, I leave them blank, but you can see in section "Art Direction")

In my opinion, it depends not only on the art critics that detect stylistic similarities and defining the various schools and trends, but also on the willingness of the artist to define himself in any way, to emphasize its connection to some place with a certain style, etc. d.. The fact of birth or even the school itself is not significant.
