I'm an unmarried mom who want's to go on a trip with my 4 years old daughter next summer,were traveling to Peru and i just submit her passport application without her dad signature because he left us when she was 10 months and i don't now where can i found him,since then,i'm the only one taking care of my daughter,we never married but he did sign the birth certificate. I explain that in the passport application hoping that they approve it.Now my problem is that i also need a consent letter from the "other" parent,that's for the airline (Spirit) also Peru required the same when is just one parent traveling.What can i do to solve this? What is the best and fastest way to do it? If i have to go to court,how long time usually the process takes? Thanks.
