it IS a pile of paperwork to get an extension based on marriage using legal income from working here. BUT once you and your employer do it the first time, it's just new documents of the same things over and over every year.
It's NOT beyond the ability of an average semi-clueless foreigner but you do need quite a bit from your employer and most people fail because of the documents the employer is required to give you not from the stuff they have that they provide
