I will be traveling in and out of the US four (4) to six (6) times a year for the next foreseeable future. Is it worth getting the BCP Global Entry or similar product? By worth it, I mean does the time saved really make that large of difference? Last time I went into the US via Houston, and it took a few hours to make it through. But I might have had a bad background on a bad day. Also; how long is the card valid for? I know here is a fee, and thats fine. Any other personal experiences good or bad are greatly appreciated. Thanks.
