hi, just wanted to ask, which one should go first? Do we need the visa to be stamped on the passport first or we need to do the changing of names and stamping of the visa simultaneously? Cause my old passport with visa stamped in it will be expiring on the 31st of March, and base on your experience it will be taking minimum of 2-3 months, I am just worried that my old passport will be expired when I finish the whole process..

thanks
