You mean as family member of an EEA citizen? While it's not the preferred method by the Home Office, who would rather you got EEA family permit first before applying for residence card, you can actually apply for residence card, provided your partner is a qualified person, exercising EU treaty right in UK.
Thank you joppa. I know me or my husband would have to apply on his behalf, it is the same I just did for the tier 4. Ok, I will ask my husband to apply on our child's behalf, and I will write a consent letter to say I will be there studying and that my husband and child are coming too. Thanks again.If he is under 18, you will have to apply on his behalf (completing the paperwork). though it's still HIS application. On the application, you will have to give your consent. He should be entitled to EEA family permit, as he is your (EEA partner's) dependant. Get your husband to write a letter stating he is exercising treaty right in UK and would request EEA family permit for him so that he can join in UK.
