Hi My name is Vinay Amaranatha. I have sent my paperwork for my wife's Non-EU/EEA Certificate to HMRC at end of October 23 and haven't heard anything since then. I have been getting letters from German tax Authority requesting these signed papers from Belfast. I have sent a cover letter along with non EU/EEA document to HMRC belfast office. I tried calling 0300 200 3300 several times but this is diverted to a call center and no one was clear what this documentation is or who can help with it. Could anyone please help with this request? Is there any phone number/emial ID for Belfast local office so that I can check directly with them
