Question:

I have been traveling through Europe for the last 110 days.

I will spend about 22 outside of Shengen, however my 'passport' cannot prove it.

For example, I drove into Switzerland 5 days ago and just left this morning. In both cases I was just waved through everywhere.

I fly out of Germany later this month. If I get an over zealous agent claiming I overstayed what can I do? I did keep all the hotel receipts with dates for my non-Shengen visits. Should that be enough?

Thanks.
