Travel to USA from Germany

[dileep2021]

Folks,

 

I am an Indian Citizen living in USA on a valid stamped H1B Visa until Jan 2017. I applied for Schengen visa and was issued from Aug-11-2015 to Feb-06-2016. I would like to know if I need any additional documents with regards to boarding flight in Berlin Schonefeld (SXF) and travel via Keflavik (KEF) to USA ( boston). Also, will there be any concerns if I travel from Berlin to USA on H1B visa? I have read multiple things about boarding flight in Germany. So, I am trying to clear things. I tried to read through this form but I wasn't clear.

 

Please help!

 

Thanks,

Dileep
