Is it possible if i marry with saudi man?

Hi everyone, i have a relationship with saudi man for almost 6 months. And we are finally decide to get married. He is working as military pilot. But he said there is an issue with his job regulation to not marry with foreigner.  Is that possible for me to marry with him?
What is the consideration for saudi man to marry with foreigner?
And what should we do to make everything happen?

Thank u in advance

The only condition I was aware of was that the foreign woman had to be a certain age, for example if the man is 40 the woman had to be no younger than 25 or older than 55 (could be incorrect age gap)
If he's in the armed forces they could well be regulations he will have to follow due to security risks
Some countries don't allow military staff to marry whilst serving
