You have mentioned numerous times that you have DO have documentation of your salary, what they withheld, etc . Please see below:
"Oak let me tell you what I have , I have statements from my employer about income my job , I have job contract , what I need more do you think is enough , but most of my work through the phone and inter net I don't not think I have enough proof for that ."
"I have documents says I am working for them , how much salary I get form them per month and net and gross amounts ."
I see that you have asked this question before, and each one of us has told you to use the information you have to create a substitute W2 with the information your employer sent you. Here's the link: Form 4852, Substitute for Form W-2, Wage and Tax Statement ...
Where you are hung up is that IT DOESN'T MATTER HOW the information from your employer .....even in the US different employers use different looking W2 forms......
As long as you have the information need to fill out a substitute W2 then there is NOTHING MORE you need f from your over seas employer.......there is NO blue print on how the IRS wants your employer to document your wages.I work with people from Canada, Pakistan, Iran, Australia, etc.......EACH country has a different way (and paperwork) to record the earnings. However, once I put the earnings, withholdings, etc on the Substitute W2, then, because you have to answer where you got the information to fill out the substitute W2, I state
"from country's (I name the country) documentation of wages, etc
All you need to do at this time is create the substitute W2 from the documents you have....the substitute W2 is already in the format that the IRS wants
I think you have everything you need and you're going to be fine
