My husband and i and our 2 children recently moved here with my parents . the plan when we came here was as an extended vacation for one year we were advised to use our e111 as we could not apply for an e106 as my husband did not qualify as he did not pay enough national insurance and i was a house wife .We are quite happy to use an e111 but our children started school here and they are asking for a social sercurity number . In order for the children to go to school do i have to have a social sercurity number? We did not want to register untill we had been here a year to make sure we like it here.
