Question about tax docs for H1 stamping

[Salm]

I have an appointment for H1 visa stamping at Ottawa in a few days. I have my W2's with me in case they want to see tax documents.
But now I am having doubts if it is enough to show W2?! Should I also keep IRS's 1040 form as well?

I have another question about I-797. All websites say that they need original I-797 form. I do have original. But now my friend is saying that I only have I-797A (my copy), while they need I-797C (employer's copy).
Do I need to ask my employer to give me I-797C?

=> Actually, you must provide Tax returns & W2s for all the years you worked in US. If you have enough salary details, do not hesitate to keep them.

I have another question about I-797. All websites say that they need original I-797 form. I do have original. But now my friend is saying that I only have I-797A (my copy), while they need I-797C (employer's copy).

=> I think any original of I-797 will be fine but make sure w/ your employer.
It make sense to submit your copy as employer's won't release their copy, if there is any.

Good Luck...
