Two weeks ago I went through the portal, completed what I could and paid $175 at the end with usual notice re: contact for anything missing. I do not remember that there was a vaccination question at the time. Today my wife completed her application, responded yes to the vaccination question, got her application number with notice of review, but was not asked for payment. So post May 15th is there no charge if vaccinated? Or will that come in a few days when the negative PCR is posted?
