DS-157 Employer details related

[h1b_applier]

I worked in company A from Nov 2006 to May 2009 and
from May 2009 i am working with company B
so, in Question 12 of DS-157 form regarding employer
details
should i fill the details of company A only, which is
my last employer or should i fill the details of both
company A and company B (my current employer)

as it says "Not including Current Employer,List your
last two employers"

so i am confused should i include or not include
company B in Last two employers list as it is my
current employer.

or whether it is necessary to include details of
atleast 2 employers even if it means including current
employer.

If you have just one employer you can give details of that employer alone.

Many people work only for one employer throughout their career, in which case they don't write anything.
So don't worry about number.
