Client is an expat with multiple employers.  Form 2555 diagnostic says for each social security # only one Form 2555 is allowed.  I researched and I need to put all income on same Form 2555 and provide support with a breakdown of totals for each employer.  

If I put all income on the same Form 2555 and upload attachment with breakdown can I still efile?  Will the IRS accept this?  Client is in UK and trying to avoid the hassle of mailing.
