Control for country if origin in panel data

[Jodie Lewicki]

I have two countries and different companies in those countries. I try to run a panel data regression analysis after declaring my data panel data. I use this command so far: xtreg dependent variable independent variable, fe after I checked with the Hausmann test.
However, I now got the task to control also for country of origin. And I thought that I could just give one country the dummy variable 0 and the other one 1, but when I then try to run the regression using
xtreg , dependent variable independent variable control variables dummy variables, fe

it says omitted for the dummy variable part.

Any idea how I can control for my country of origin?

Jodie:
it makes sense according to the -fe- working logic, as long as -i.country- is, in all likelihood, a time-invariant predictor.

[Jodie Lewicki]

But why does it say 0 (omitted) for the results then? So how can I really control for country of origin?

[Carlo Lazzaro]

Jodie:
as the country of origin is time-invariant, the -fe- wipes ot out.
