I filed E/I-765 in Sep 23. USCIS did not ask any document when I applied it.
And I was tested Biomatrix on Oct.
Somebody said me I should sent OPT I-20 to USCIS.
Sould I send new I-20 by mail?
You should check the requirements on I-765. If it requires than you need do. Did it ask you send it when you filed it electronically ? If not, then you do not need to. You can couble check with your DSO to get confiramtion on the same.
