Input: Consider Input: I'd like to see the Catacombs of Paris in September 2017. It appears that tickets can be purchased in advance from http://b12-gat.apps.paris.fr/accueil.aspx ...  is the demand such that purchasing tickets in advance is necessary if you want to see it?

Input: Consider Input: I have a newborn in Cambodia and finally got to the point where I have a Lithuanian passport with Cambodian exit visa stamped in, valid for 7 days. I will need to leave the country with the baby and then come back and get him an E class visa upon entry, which then can be extended forever. I spoke about this yesterday at the immigration department and they seemed to be ok with the plan below. However from my personal experience I know that things at the border don't always run so smooth...

This one is tricky, as normally no one does visa runs in Cambodia since you can get indefinitely extendable E class visas. Still it is worth asking (and I have a slight Asian border-crossing phobia). I am planning to cross the Vietnamese border with the baby, while his mom will wait at the border to save on Vietnamese visa. Also, her Cambodian visa is 3 month single-entry. Then I get Vietnamese visas for me and the baby and then head ASAP back (baby is 3.5 months old and he has boob addiction. I have a bottle of formula, but he doesn't like it much. Also he hasn't been away from mom more than 10 feet ever). When doing visa runs is it wise to stay for some time in Vietnam, or can I cross immediately back and no one is going to blink an eye?

How long do I need to stay in Vietnam when doing a visa run from Cambodia for a baby to be on the safe side?


Output: How long do I need to stay in Vietnam when doing a visa run from Cambodia for a baby?


Input: Consider Input: Some Islamic countries in the middle east has got a long history of trying relationship with the west, and with terrorist attack of ISIS being a real threat to the world, would travelling to middle east put me in some kind of monitoring list of EU? Would that travel history bring me trouble if I need to get through EU immigration?



Output: Can the history of travelling to middle east (Iran) hinder you traveling to EU again in the future?
