An IOE is the office or location, who receives applications from the lock boxes (if you file directly to the service center then your application status will not show IOE) and does initial check such as application fee, completeness etc then sends to the respective service center depends on application and work load of each service center and jurisdiction. I hope this information helps. IOE is not a service center itself, just facilitates the application allocation process.

Now lets come to the next point, this is US and every one has freedom, does not matter a nepalese guy marries with a BBW or nepalese girl dates black guy or white guy/desi/pakistani etc I have found we Nepalese people are the most nosiest people in the world filled with hatred and jealousy. This is why our country Nepal struggling since decades and will be enduring forever.....
