If you are frequent travelers, and running low on your US passport pages, we recommend you to request additional passport pages. The specific reason behind it the additional pages service will be discontinued at the end of 2015. Although the US State Department has not yet put out a formal announcement but many media outlets reported the same. The time is to act now, have pages added to your passport if you still have several years of validity or renew passport by requesting a large 52 page book at no additional costs.
