What's the correct format for a character that speaks Spanish? Like this:

MIGUEL
(in Spanish with subtitles)
Hello. I'm new here. Where
can I get a job?

And if this character then switches to English should it be like this:

MIGUEL
(in English with subtitles)
I can speak a little English.
I lived in Texas for a year.

Are there abbreviations for this stuff?
Thanks!
