Need Urgent help in filling DS 160 form

[Swati Gupta]

Hi,

I am a software engineer applying for B1 visa going to attend a conference in US.

I have some doubts in filling this form:

1. What should be entered in home address ? Current address as i am living on rent or permanent address.
2. What should I select in travel companions ? Travelling with 3 colleagues if all of our visa get approved.
3. In previous educational/training details, should i enter all school details above 8th standard or just 10th 12th class ...date of attendance separately.
4. What should i select in primary occupation ? Engineering or Computer Science Both seems correct.

Thanks
