Given a travel related situation, and given a specific question about the situation, summarize the question into a title

[EX Q]: I am non-EU family member married to a Romanian citizen. I am currently residing in Romania and I have temporary residence card here. As Romania is in EU but not in Schengen area, can we travel together visa-free within EU and Schengen countries ?

[EX A]: Non-EU family member traveling to Schengen countries?

[EX Q]: I'd like to go visit Istanbul in one of the next weeks; I'm not scared by it (I mean, things can happen anywhere), just concerned about possible consequences of taking photos.

I've heard a few third-hand reports about police -- before the coup -- being a bit harsh on photographers. Is it still the same, or even worse than that? Perhaps it has never been like that and those reports has just being exaggerated? I can evaluate how much risk I am prepared to take if I can get access to current information about the police.

I'd obviously avoid sensitive targets (policemen, military personnel and buildings). But I like to take photos of common places, too, so while I'll probably take photos of famous buildings I could take shots of common houses, telephone boots, generic skyscraper...everything that can make a good shot. But then, I've heard (from a friend of a friend of a friend...) that you can get in trouble with police if they think you are shooting things that they think are not interesting and thus you are not supposed to take photos of.

[EX A]: Can photographs be taken in Istanbul as of August/September 2016?

[EX Q]: As usual, lots of fake/spam sites when trying to Google this. And also information that is out of date, applies to other nationalities only, or applies to getting the visa in another location.

Often there are different rules for applying for a visa depending on your nationality, or on which embassy or consulate in which country you apply to.

I also believe that the requirements for a multiple-entry visa may be more stringent than for a single- or double-entry visa, depending on your nationality.

I want to know what documents I need to take to make my visa application in Saigon, Vietnam, in 2015.

I obtained a double-entry visa just over a year ago in Vientiane, Laos and only needed a passport photo and printouts showing one flight in and out of China and one hotel booking. A travel agent in Vientiane booked, printed, and cancelled those for me for $3. I didn't have to book anything for the second visit.

I believe I may have to show that I've visited twice before to be eligible for a multiple entry visa. I have a new passport since those visits and did not bring my old passport. Is it up to me to provide evidence of my previous visits or do they just check my records? Will I at least need the dates?

What is the current price?
How long does it take?
What do I need to provide?
