L1B visa interview - Documents needed.

[suviswan]

Hi All

My visa interview is scheduled on next week. Many of the people have mentioned about I129 form. I have couple of questions on it

- It was applied by employer. The employer has sent me the scanned copies of the form that was applied. But there is no receipt number in the document. Is the print of scanned copy sufficient ?

- They sent me the original I-797B . It has some receipt number. Is this sufficient ?

- Photographs - How many should i carry ? Is there any specification for that ?

Thanks
