I'm confused. You said in your first post that neither you nor your spouse is working, and that you plan to borrow 30,000 pounds to prove maintenance for your ILR. Now you're saying that your spouse IS working but is considering quitting because you don't need the money? Obviously you do need the money, or you wouldn't be considering a £30,000 loan. Why doesn't your spouse just keep the job until the ILR application is finished?
