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

[EX Q]: Is it possible to visit Old Goa (for a day trip) from one of the beach resorts? How long would a taxi drive take and how much would it cost? Or is it better to spend a night or two in Panaji, and then move to the beach?

[EX A]: Is it possible to visit Old Goa from the beach resorts?

[EX Q]: I recently applied for a short-term student visa, mentioning the departure and return dates as 13/05/18 and 10/08/18 (=90 days) respectively. After my visa got approved, the validity dates mentioned were 11/05/18 and 08/08/18 (=90 days) but since I have already booked my return flight on 10/08/18 and if I return back from France on 10//08/18 I'll be violating the visa policy. 

What will be the best thing which I can do in this scenario? 

If I go with this visa and violate the visa policy by exceeding the visa's validity by 2 days what consequences can I possibly face, considering the face that it wasn't actually my fault but a sheer mistake committed by people in embassy?

[EX A]: Can I stay in France more than the validity range of my Schengen visa given I'm not exceeding my duration limit?

[EX Q]: 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?

[EX A]:
Travel to USA using a passport that does not scan properly
