Both schools are accredited, so they’re both safe and reliable options. GoElite works closely with both Texas WU and Westcliff, and the CPT application process with either school is smooth.
That said, I’d recommend considering other factors. Personally, I’d suggest Westcliff. It offers a wider range of majors and is located in the heart of Dallas, TX, which makes it more convenient in terms of location and accessibility.
I have a friend who enrolled at Westcliff and got H-1B without an RFE. Seems pretty legit and convincing to me.
Don’t know much about Texas University—will wait to hear more from others.
