- The person at the Lufthansa counter accepted the combo EAD/AP card
- The immigration official at Indian customs examined the card closely, looked at my expired H1-B visa stamp, asked me if they would let me in with this card (I said yes) and then let me pass
- At Frankfurt, I was asked if I have a visa, I said "Yes, a German visa" (I had a one year multiple entry German visa). She did not flip through the passport to actually find the visa, she just let me through after looking at the front page. Current regulations state you need a transit visa if you are on AP and are not from one of the visa waiver countries.
- At US immigration I was asked to fill out the white I-94 card and sent to secondary inspection
- At secondary inspection the lady asked a few questions about my specialization and then stamped the I-94 card as "DA/AOS" and let me through. She also "Cancelled Without Prejudice" my expired H1-B visa stamp
- I did not have to show any documents other than my passport and EAD/AP card to anyone.
Python's context managers are a very neat way of handling code that needs a teardown once you are done. Python objects have do have a destructor method ( __del__ ) called right before the last instance of the object is about to be destroyed. You can do a teardown there. However there is a lot of fine print to the __del__ method. A cleaner way of doing tear-downs is through Python's context manager , manifested as the with keyword. class CrushMe: def __init__(self): self.f = open('test.txt', 'w') def foo(self, a, b): self.f.write(str(a - b)) def __enter__(self): return self def __exit__(self, exc_type, exc_val, exc_tb): self.f.close() return True with CrushMe() as c: c.foo(2, 3) One thing that is important, and that got me just now, is error handling. I made the mistake of ignoring all those 'junk' arguments ( exc_type, exc_val, exc_tb ). I just skimmed the docs and what popped out is that you need to return True or...
