Naturalization?

Yvonne asked:


I’ve lived in the states since I was 12. I have a green card, am married and have to american-born kids. I started my naturalization process last year and received an interview date. I had to cancel because my husban’s job forced us to leave the country for a few months. I wrote INS a letter informing them of this move and asked to put my stuff on hold. When we returned, I wrote another letter asking them to reschedule my appointment. I’ve been waiting for months. I called them today and they say they never received any of my letters. They said I should go to my local INS office and see what’s going on. I plan on doing this, but I’m wondering if the application can run out? I’ve already sent them my $400 or whatever it was. Does it expire in a certain time period if nothing is done?
We only left for 3 months and I’ve accumulated over 15 years in the states.
