I am filing Green Card petition for my husband. I studied over the IRS website and find out my tax return should be filed as “ MFS”. How many years I need to file 1040x.

It depends.  If you elected the wrong filing status on your tax return, then a 1040X should be filed for each year there is an error if all years will generate additional tax due.  However, if you will receive a refund for all the amended returns, then you are only able to amend 2014 and later.

Amending to claim an additional refund:  You can amend tax returns for up to three years from the due date of the originally filed tax return to receive a refund.  This includes 2014, 2015, 2016, and 2017.  

Amending to pay additional tax:   Amend all tax returns as soon as possible to correctly report your income and pay the tax liability as well as the penalty and interest due.
