I’ve extended my marriage visa the same way. No issues if u have it seasoned for 2 months prior to applying. Even it shows in ur book bank or statement about local transfer, no problem at all. Good luck
I’m on a marriage visa non-O. U don’t have to leave to renew it. U just need to keep 400 k for 2 months prior to applying. Submit ur marriage documents, address, wife documents ( id, house book) hand drown map of house location, pictures of in and out side of ur house with wife etc. easy process I would say. If u r working with a work permit, u will need loads of documents from ur employer.
