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

Example Input: I am going to be in Osnabruk, Germany till August 23, 2012. I would like to take an excursion to Amsterdam. Are there bus excursion operators in Osnabruk that offer Amsterdam tours? (maybe some network which operates all over Germany). 

Example Output: Osnabruk to Amsterdam excursions

Example Input: I am opening up this thread to know from fellow travelers who are planning to visit tje EU (Spain in particular) from the US. I plan to travel somewhere in December 2018 around Christmas time, go to India after staying there for 7-10 days, and return to the US by the 4th week of January.

Do I need to apply for a Schengen visa in advance, or can I get visa on arrival as I am a valid US non permanent resident? Also, I do not have an H-1B visa stamped in my passport, but I have an approved I-797A (Notice of H-1B visa approval). 

Please let me know if something is not clear from my end, looking forward to hearing.

Thanks.

Example Input: I have been invited to a conference in USA. I am going to apply for a B1 visa. Unfortunately the invitation letter doesn't have a signature on it. Only the email id and the website is there. Would the letter be valid in this case?
