EHIC and CIS

[leyu]

Hi,

Can an EHIC (issued by a foreign government) card be used to prove CSI coverage on a certain period? I understand it only applies to people living in the UK on a temporary basis. At that time I was a foreign student and was going back to my home country outside uni periods. Does that qualify as temporary basis?

Furthermore as my EHIC does not cover all the period I was a student for, does an official from my government stating I was covered on that period and a mention of the medical agreement between the Uk and my country enough? (this is regarding UK naturalisation process with settled status).
