My DH (let's call him Mr. Alaska) and I both work full time, and pay income tax like everyone else, which goes towards our use of the NHS like everyone else. We've just found out that we need to fork out a £500 surcharge for his use of the NHS as part of his extension of his immigration visa (for being my husband of 5 years, and father of our 18 month old DD - both she and I are British, though I guess she's sponging off the NHS quite a bit). Am I being unreasonable to think it's unfair that my DH has to pay twice?
