As if filing taxes wasn't a good enough reason to hang on to your old pay stubs, thousands of Mexican guest farm workers are discovering another reason: back pay.

As the New York Times reported Monday, the governments of the United States and Mexico are working to give the 2.5 million braceros a one-time payment of $3,500 for long overdue withheld wages. One problem is that many of the former migrant workers who came to the United States to work in the program from 1942 to 1964 are either dead or in their old age, and are having difficulty tracking down the documents they need to prove they were in the U.S. about 50 or so years ago.

The Mexican government took 10% of the braceros' wages to hold until their eventual return to Mexico. But many didn't get it back, and in 2001 a group of braceros from the World War II era filed a federal lawsuit against Mexico. The government announced a reparation program in 2005, but required braceros in the United States to travel to Mexico to register, a difficult journey for the elderly and infirm, the Times reported.

From June on, the choice will be a) carry a passport or b) don't go. The smart ones (this describes you, right?) will brave the bureaucracy and get their passports right away before the system gets jammed with applicants. The first quarter of every year is always the smoothest time to get or renew a passport with a minimum of grief, with the average application taking only a couple of weeks. Don't wait longer than March, though, because by the spring, the paperwork logjam is sure to be extreme considering the twin demands of summer travel prep and the frenzied run-up to comply with the long-delayed rule.

Why the requirement? Lots of people think that the government just wants to make it easier to spy on our movements. I don't know if I agree with that (or if I did, should I say so in print?), but there is no doubt that security is driving the mandate. There are currently some 7,000 types of birth certificates in circulation right now, so presenting one of them, plus a passport, currently clearly presents some validation issues for border agents.

Even though these men and women are first and foremost legislators who shape the face of our legal system; many of us take for granted the "little" things they can do for us. I know up until a year ago I had only a faint notion of what my congressman did outside of legislating, but that all changed when I ran into consumer issue that even I could not fix. I soon found out that my local congressman was severely underrated; on top of representing my interests in legislature, he also provides me many other services.

The formative experience that made me realize how much I had underrated my congressman was when I had trouble consolidating some student loans. After numerous phone calls to both lenders with no results I reached out to Jim Jordan, my local representative. His office was able to get in touch with the right people and get the loans consolidated within a matter of weeks; saving me close to $300 a month.

On top of that helping you with student loan disputes they can also:

• Help with federal agencies such as housing, Veterans' benefits, Social Security and Medicare.
  Arrange tours at points of interest in DC.
• Assist with Passport and immigration issues.
• Nominate you for a U.S. Service Academy such as West Point.
• Help you get a Congressional internship.
• Provide you with a flag flown over the U.S. Capitol.
• Congratulatory letters for birthdays anniversaries, retirements and more.
• Assistance requesting federal funding.

Well, here's a cool idea. I can't believe the federal government thought of it and actually made it happen.

For Americans who travel a lot across borders by land or sea, say to Canada, Mexico, or on Caribbean cruises, the State Department is now issuing zippy little Passport Cards, which are sized for wallets and contain the mandated (and controversial) RFID chip that makes crossing borders much breezier.

Makes sense to me. Booklet-size passports are vestiges of an earlier age, back when we traveled with steamer trunks and dollar notes were as big as hankies. Passports are also easy to lose, partly because they don't fit in wallets and partly because crooks can easily spot them. Having a high-level federal I.D. in your wallet at all times can also be mighty handy. Bouncers and postal clerks may quibble over accepting that gym membership card, but it's hard to argue with a passport.

According to the U.S. Department of State, you use the same supporting I.D. documentation for apply for a passport card as you do for a traditional passport, which means once you've got one, you're vetted, and you can use it to apply for a booklet passport later on if you want. You can even apply for both the booklet and the card at the same time without having to pay an extra execution fee or send more photos (just two will do the trick for both).

Beyond belief, it's starting to become fashionable to visit places for the enjoyment of watching the local menfolk brandish deadly weapons. In Italy, soldiers in body armor were recently deployed to stand vigil around potential terrorist sites. The Financial Times reports that in Rome, where a thousand of them appeared this summer, patrolmen quickly became tourist fodder in their own right.

It's not just in Italy, either. There is almost no other reason to visit the border between North and South Korea than to gaze in admiration at the trigger-happy sentries who mill along the DMZ, and yet each day of the week, coach tourists make the day-trip from Seoul to do just such a thing. (Of course, it doesn't always work out -- in July, one clueless tourist was shot dead by North Korean soldiers after she wandered away from her border resort.)

Berlin's Checkpoint Charlie, an emblem for oppression and woe when it was a militarized link between East and West Berlin, is now a tacky tourist ghetto where visitors pose for snapshots with actors dressed in fake army getups. Old-timers are outraged -- there's no museum there to supply context.

And why not? Cops are plentiful, intentionally conspicuous, and above all, free to admire. And often, their style varies as much as the cultures they protect. These days, a locale's demonstrations of defense says as much about its modern society as its cuisine.
