What should a 36-year-old man do, married and residing in Saudi Arabia for six years, who holds a middle-level qualification that prevents him from bringing his wife over, and has only two options: bribery or forging a university degree?

You must fear Allah and abstain from unlawful acts such as lying, forgery, cheating, and bribery, because the Prophet, peace and blessings be upon him, cursed the briber and the bribed, and forbade false testimony and cheating. Whoever fears Allah, He will make a way out for him, ease his affairs, and suffice him in what worries him. These unlawful acts are not permissible unless a person has a right that he cannot obtain except through them, or in dire necessity where a person faces destruction or a severe illness. This does not apply to your situation.
