Sorry I ask this question in the wrong forum
– If somebody could share his/her experience about this, I really appreciate it. Thank you in advance…
I am a GC holder. My parents have visitor visa that still valid until next 5 years in their passport, and plan to visit us in August.
Can they travel to Canada or Mexico or any other countries from US, and come back to US again?
Has anybody ever done that?
Will Immigration officers at the airport give them hard time?
They will get new I-94 – will new I-94 be valid for another 6 months?
Please share your experience with us…THANK YOU!!!
