Travel to US with Attestation form
I'm a US citizen planning on traveling to the US for a few weeks. My Swiss student visa was for Sept.-Nov., meaning it's expired. I have the Attestation of Residency stamped form, stating that I am a resident in Lausanne since September. However, I have yet to receive my residence permit. My question is, can I travel to and from the US with this form and my passport? (The Canton of Vaud is notorious for 5-8 month wait times for a residence permit, so I'm assuming it won't arrive before my trip).
Side-note: I traveled to the Netherlands and the UK with this form without any problem, but I'm not sure if that was just luck. Thanks!!!
