Recently I attended a free presentation on 'US citizenship aplication' process by a charity organization in our public library. One of the point it was mentioned that if it is applied through lawyer or some body authorized by US Immigration services , we get citizenship significantly faster .( 18 months vs 9months through lawyer ). I can't say that it is a sales pitch as the presenter who her self is not a lawyer associated with a charity group and authorized to apply only charging $60 for filing. so there is no significant money involved( w.r.t to the faster times ) for this process. I could n't cross verify this information from any other source ?. Does any body information on this ?. I appreciate the feedback.
