Can I sign a French tourist visa again if I refuse it?

You can sign a French tourist visa at any time after it is refused. It has nothing to do with the time, mainly depending on whether your overall binding force has been strengthened. As long as the binding force has been strengthened, it can be signed at any time.

In fact, whether the French tourist visa can pass depends mainly on whether we can convince the visa officer that you will definitely come back when you go to France. If the visa officer believes that you will come back after going to Europe, he will give you a visa.
