Oman does not have a concrete statutory policy in writing about criminal records. Omani authorities make a decision based on:
-how long ago the conviction was
-the nature of the conviction
-the seriousness of the facts
-whether or not there have been criminal acts since that conviction, and
-whatever else the authorities believe to be relative.
Generally speaking, 20 year old felony should not in itself be an issue given how long ago it was, provided it was not a felony based on violence or of a sexual nature.
I hope this helps and clarifies. Please use the SEND or REPLY button to keep chatting, or please RATE when finished. You may always ask follow ups at no charge after rating. Kindly rate my answer as one of TOP THREE FACES/STARS and then SUBMIT, as this is how experts get credit for our time. Rating my answer the bottom two faces/stars (or failing to submit the rating) does not give me credit and reflects poorly on me, even if my answer is correct. I work very hard to formulate an informative and honest answer for you; please reciprocate my good faith with a positive rating.
