My eldest son is a British. he is 16 year sold (grade eight). his father passed away 16 years ago. we are in Malaysia. My son never reside in UK nor do I. I have 2 other children from second marriage. I want to send my son to complete his GCSE/study in UK. But I have no one to leave him with in UK . What visa should I apply for me and my other 2 children if we were to live with my eldest son in UK. is it better to apply from outside UK or apply within UK? Anyone in a similar situation and managed to secure something? I just hope to be with my son, while he learning to live in UK (at least until he mature enough).

Thank you for the feed back
