Wife alimony and child support before and after divorce

Husband has been on visit visa for about 1 year + and has not got any permanent job. He has zero balance in his bank account.

Question: 1. How will this affect my alimony and child support case? How can I demand this from the judge?

2. Aside from this, can I still file a claim for 3 years of alimony because he did not provide for our family since we got married?

I am working and has been the provider to the family. Our divorce case is still ongoing.
