No. You should not go to US embassy for visa.
It is not because, your husband will not give you all supporting documents for you to get Visa.
It is because, you and your family should earn back the trust from your husband if you really believe that your husband is good person and you will live happily with him.
TRUST is everything in any relationship.
There are many other communication channels other than talking in person.
Send a letter to their address. A real respectful letter to your in-laws.
A heartfelt love letter to your husband. You can write more letters.
Find some of his friends and send messages through them.
But, all this will succeed only if your intention to join him back is real and genuine.
If there is a reason for your husband to file divorce based on cruelty and if it is true, then you should be bold and open enough to tender apology for the same.
Else, if all the fault is with your husband and his parents, then you should really have a big heart and lot of patience before getting them back.
After trying all other options, may be if you can make up your mind, go for "mutual consent divorce" so that both of you can get divorce in 6 months and a start a new life.
