Multiple Entry Rule

[sach_sonu]

Hi There:
My Parents have multiple entry visa for 10 years. I want to know if there is a stipulated gap required between their first visit and second visit. Something like you can not come back for 6 months after your departure from USA the first time.?
Please let me know. Appreciate your response!

no gap requirements - u can travel as long as the visa has a valid unexpired date
on every entry u can get max 6 mths stay at POE.
