H1B - Docs - mistake in experience column

[H1B_Aspirant]

Hi,

Please check if there is any problem with this.
I have-been working with company.X for 3 years till july 2008
and in july i changed to company.Y in singapore. But in my H1B
petition my US employer menmtioned it as 'working in X'
I have all the supporting docs (experience letter,relieving letter,payslips)
for company.X. and offer letter from Y & pay slips , ID card,bank statement

Should i get the doc ocrected to 'working in Y'? please kindly suggest as i am planning to go for stamping in december.

Thanks in advance
