Explaination of refused U.S. Visa

Hello I am applying for H4 dependent visa. I am filling the DS160 form for dependent visa now and I am not married currently but the person I am getting married to (his name is rahul) has H1 visa.

Before in april 2012,I had applied for Tourist visa to attend convocation of rahul but it got rejected under 214(b). So what should be the answer of this questions?


				Have you ever been refused a U.S. Visa, been refused admission to the United States, or withdrawn your application for admission at the port of entry?



Also what should be the intended length of stay in USA on dependent visa. Should be a small duration like 3 months or 6 months or should it be the expiry date of my husband's H1B visa.

The home address should be the address mentioned in my passport or should it be my husbands address or it does not matter what address I put?

Thank you in advance for answering my questions.
