No, having a U.K. visa won't hurt your chances. In fact, it can sometimes help. It shows you’ve traveled internationally and followed other countries' visa rules. Just focus on showing strong ties to Zimbabwe and your ability to pay for school in the U.S.

I have a friend who is also from southern Africa and had a U.K. visa when they applied for my F-1 visa. The U.S. visa officer didn’t even mention it. What matters most is that you explain your study plans clearly, show financial support, and convince them you’ll return home after your studies.

The U.K. visa isn’t a problem at all unless it looks like you’re trying to use every visa just to leave Zimbabwe permanently. Be prepared to explain why you’re choosing the U.S. instead of the U.K. for school. It helps show that your plans are real and well thought out.
