Yes, that'll work just fine. ES doesn't care which country its clients are in.

Well, the usual limitations of the speed of light and available bandwidth obviously apply. You might want to tune the batch size of the elasticsearch output to avoid the round-trip delays you get with too many smaller requests. But ultimately the TCP windows is limited in size so you may need parallel TCP connections to increase the throughput beyond a certain point.
