rmxyz,

One of my friends got her spouse in the US last Dec. He told me the whole visa process went very smoothly.

1. When my friend was applying, the application fee was $100 each, so it's $200 for him and spouse. When in H1, you don't have to pay visa fee unlike for F1 applicants.

2. If you're sponsoring your spouse, you've to show the bank balance, not your spouse's. Your bank balance from US should be good enough.

3. Yes, your spouse have to fill the application form online and print it out. If she isn't computer-friendly, then I'd suggest you to do it and send her along with your bank balance. She'll just sign the form.

Note: Don't forget to send the petition copy of your's and your spouse.

Hope this helps!
