Apologies if this has already been answered but I couldn’t find it. Hence posting the question.
My parents came to US for the first time in May this year (5th May to be precise) and left after 4 days. The plan was to stay for 4 months but we had an emergency back home and hence they had to leave. Now they are planning to come back again in July. So I just wanted to know if it is ok if they plan to come back and stay for 3 months this time.
