Marrying an Omani

Hi. I wanted to find out if an expat wants to marry an Omani man in his 20s, is it possible? Also, can the marriage take place outside Oman?
Please advise

Thank you

Oman agrees to foreign marriages given the fact that the Omani applicant fulfills their requirements to apply and these are quite fair for both sexes in fact and usually the age is not set by-law but people keep on telling that for males it's 40 and females 30 (again that's not specified by-law)

Using his/her civil ID, an application can be filed at the ministry of interior and it takes them a while to issue the permission for this marriage.
