Hi,

I live/work in Ann Arbor, MI with my J-1 visa and just entered US in May 2010. My wife lives/studies in Boston, MA with her F-1 visa since Aug 2009. When we file tax report for year 2010, do we need to report under "married filing separately" or "single"? It seems like that reporting under "single" makes easier our processes. Can each of us be a head of household?
Thanks,
M.I.

If you are married, you cannot file as single anymore.
You are both non-resident aliens and would need to file as married filing separately. You cannot file as head of household.
