Opportunity to work in the US - 2nd test

So, you get to wear the cool uniform and the funny hat?

Here’s another option for a US master’s degree in engineering. Do an online program. There are very reputable online programs from Duke, Georgia Institute of Technology, Colorado School of Mines, and many others.

They are designed for working professionals. In the US, engineering majors are snapped up after their four year BS program, and often even start working for companies as undergraduates. Most don’t bother with master’s degrees, but for those that do, most work and have their employers pay the tuition (it’s call tuition reimbursement; most large US companies offer it.)

Get your degree, go to work, get a US master’s online and have your employer pay for it, or fund it yourself.

Don’t want to do that? Need to study in the US and you need money to do it?

Apply for PhD programs in the US. An engineering degree will admit you to all sorts of science PhDs: computer science, applied math, materials sciences, nanotech, biotech, physics. These programs are fully funded. Don’t take admission to any program to any program that doesn’t pay you as a research assistant (best) or teaching assistant (worst.)

Want a nearly automatic admission and low cost of living? Look in the middle part of the country, and skip the coasts.

Unless l’X has a special agreement with a US University, you would need to spend more than a year to get your Master’s degree there.
My advice would be to pick the highest ranked international university that has a Cat.1 partnership where you can also develop cultural and linguistic fluency, complete your 4A abroad with the highest possible grades, prepare the GRE, and dlearly during 5A apply for a PHD at universities such as Stanford. You’ll get a funded Master’s degree and will get your 2-year opt then can resume your PhD or go back to France.
Please keep in mind that in the US, the name of your school matters less than the way you used the opportunities it afforded you and what you’ve achieved yourself (research, product development, proven impact during internships, leadership and personal qualities…) as well as the good you’ve done (less so for a PhD, more so for an MBA).
