splax , what do you mean by oath eligible? thanks
That's when their 5 years (or 4yrs +1day or 3 years, depending on what basis one files) continuous residency is up. In your case (using your sig), assuming you had no breaks, the earliest oath date would be 4/12/2010. We can file up to 90 days ahead but most DOs do not schedule an oath date before that 5/4/3 yrs time has passed.
