F1 student working outside campus without CPT or OPT: Follow up

Thanks for previous help.

Could you tell me how to revise this mistake? Thanks.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Hello all,

I am a Chinese graduate student.( Having F1 Visa now ). Now I am working in a Fortune 500 company as a summer intern in US.

When this company hired me, they did not ask me for the OPT/CPT. But they still pay me to my bank account using my SSN.

I am a littl nervous that this employment may lead to a very bad condition. But when I first got this offer, I did not know I should use the OPT or CPT.
