If your trip is not within 2 weeks, but you need your U.S. passport more quickly than the normal processing period of 4 to 6 weeks, you can request expedited service by mail or in person at a passport acceptance facility near you.
The average is 2-3 weeks for a refinance and 4 weeks for a purchase. The time it takes to close your loan can be affeted by many things and no loan is the same.
also consider refinancing. Helpful to 1 out of 1 people. I was trying to do the same thing as you, lower my utliization in hopes of boosting my score before applying for a car loan. A couple of loan officers told me it can take as long as 90 days for the lessened balances to reflect in your credit score. I chose to get a loan at a higher rate now and refinance later once my cards are paid off and I have a half dozen car payments under my belt.
