My wife has a visitor visa for the US (10 year validity) which she got 2 years ago. She gave birth to our son in the US and came back along with the baby. A month ago she went again to the US to visit her grandparents but after a long interrogation, the immigration officer at the border gave her a limited stay stamp for one month and told her to pay the hospital bill (from her previous stay/childbirth) which was already waived by the hospital. She contacted the hospital and they refused any payment as the bills had already been paid by a charity.
Now my wife has returned to India before the one month time limit set by the immigration officer. Will she face any problems if she goes back in the future?
