about my husband visa

[msurani1]

hi, i done my study here this April semester and i am graduating in this coming june. My husband was rejected 3 times as a visitor visa and last time he was rejected on 9th june 2010. Now i have convocation on 14th june and so we want to put file as a visitor visa for this convocation so i have a one question regarding this, is it valid reason to put file in this convocation as a visitor visa. I also have a one question is it any quote for dependent visa, we also planned to put file after my work permit as a dependent visa so can you please tell me when my husband has to put file so he will get the visa. I want my husband for some time so please reple me as soon as possible. I will wait for your reply.

Thanking you,
Megha
