Runaway case

Good day ! I just want to ask for some advise I was terminated by my previous employer here in Bahrain and they cancelled my visa they ask me if Im going home or I transfer to another company but I still don't have an offer letter so I tell them that I go home. They give me ticket but I don't go home because I want to find a job here , they call me and telling me that they will file a runaway case to me. If there's any possibility that I can get visa from other company if I have a case like and what are the process I can do because I don't want to get in touch again with my previous employer.

If the visa has been cancelled, then I wouldn't worry. They can't do anything.

But I hear from someone even my visa was cancelled by my previous employer they can file a runaway case for me so If ever new employer cannot give or process visa for me because its blocked

Incorrect.  The case can be filed before cancellation, not after.

Hi can anyone get runaway while having visa

Don't understand your question.   But if you are asking, yes, you can be reported as runaway despite having a visa.
