PROBLEM: I am planning to travel to the US on an Indian passport. My passport is overall in good condition, but with one defect: It cannot be properly scanned at the airports. So far, I have traveled quite a few times through China and Korea without any problems. But can this create problems for me while entering the US?


SOLUTION: Travel to USA using a passport that does not scan properly

PROBLEM: After reading UK Citizen flying to US, then Canada, then back to UK - How does this affect Visa Waiver Program? I am wondering: 


If you are in the US, travel to Canada and re-enter your VWP clock didn't reset. This is classic.
There are countries, in particular in Central America where a brief visit does count as a "reset".
So what happens if you go USA-Canada-reset country-Canada-USA? 



SOLUTION: Is it possible to reset the VWP time counter by visiting a third country after entering Canada from the US?

PROBLEM: Whether traveling with a child or friend, especially in large crowds, should one take precautions to avoid losing someone?

I will be backpacking, so packing light is important; however, I still thought it would might be necessary for me to get something like a walkie talkie. I have even considered using a strap/buckle and attaching it to the other person. This sounds ridiculous, but losing someone would ruin a great portion of the trip.


SOLUTION:
How to avoid losing someone while traveling?
