Hi, we have accidentally crossed US border through Canada for visiting Niagara falls without passports. Canada immigration has formally took IDs and gave unintended visit copy. While returning back to US border, the officer asked for passports and took IDs again. He has warned us and allowed back to US. Our question is,will there be any issue while we are on H1b and F1 visa since they have taken our IDs for some verification and returned them.
Will there be any issue going or coming to US in future or now ?
Please help with the information we are bit tensed.
Thank you in advance.
