S1 form registration
My wife and I have UK issued S1 forms and we are currently going through the residencia process. We are appointed to collect our residencia documents on the 16th of December. Do we have wait to register our S1's with the INSS until we are in physical possession of the residencia docs or can we do this earlier? (after the current travel restrictions have ben lifted of course). I presume that the nearest INSS offices to Sorbas are at Huercal Overa or Almeria? Is it necessary to make an appointment? Any guidance or advice would be gratefully accepted!!
