S2 Q&A: What should I write so they don't think I'm only doing this for CPT?

Write the truth, plainly: what you want to learn, how it connects to your current or next role, and why this program. Don't write anything you couldn't repeat in a visa interview - the statement becomes part of your record, and a real career reason beats any wording trick. Send me your draft and I'll flag anything vague or inconsistent.
