I'm pregnant my baby is due in this month . I have tire 4 visa I have 2 year visa left . I want to ask if my baby is born hear is possible he or she get british passport . Because some people told me is new rules is coming this year .if your baby is born in this year you can get british passport . Is it true or not?

As far as I know, no new rules coming. If you are a citizen of a country within the British commonwealth, then you baby could acquire a British passport (under some circumstances), otherwise no.
