First of all thanx to all the moderators who have helped me over the years to get my PR.
Now i am back with another issue

I have recently applied a case for her and sent my passport to Home Office as the sponsor, i have passed life in Uk and B1 this year, the question is that since i have sent my passport to Home Office can i apply for my own nationality without the passport being present or do i have to wait till my passport is returned by HO ? I have rang NCS Manchester today and all they said is that they r not sure if i can send the application for nationality through them since i dont have the passport on me, any suggestions guys ? Shall i wait for my passport or shall i send the application ?
Thanks in advance.
P.S i am eligible for nationality on 10 of june which is next month.
