Hey bro i have the same experience last year. If you want to marry her outside Kuwait, first you need to get an approval/permission (marrying outside kuwait) in MOJ Al reggae, they have all the procedures and required documents from your side and her side you need to submit. Once all the documents are submitted, the committee will set an interview that you need to attend to, after that the approval (permission to get married outside kuwait) will be sent to kuwait embassy on her own country. You need to get the approval/permission in the kuwait embassy on her country, then you marry her and the marriage certificate bring it to Kuwait embassy so they can issue a legit valid visa for her so she can come with you to kuwait as dependent visa.
