Now you are confusing me. You state, "I was supprised you did not tell me to reopen the I-751 and deportation proceedings takes a very long time." I never told you not to reopen the I-751. In fact, most of the information I gave you was about a motion to reopen. And the motion that you would file would have been to reopen the I-751.
Now as far as telling you that it takes a very long time to deport someone, well, it does. The system is broken on both sides. It will take a few months for USCIS to send the information to ICE. It will take ICE a few months to go through it. Once they do, they will file a Notice To Appear with a date TBD (To Be Determined) when an appearance in court would be necessary. Then the court, depending on how congested they are, will assign a date for a Master Hearing. So that could take a few more months. If you want to handle it quickly, at that hearing you just tell the judge that you want to refile the I-751 with the court and explain what happened, etc, etc. So the judge will give you a few months to file everything, probably even 6 months or more (depending on how congested they are with cases) and then you get an Individual Hearing. It doesn't mean an actual deportation will occur because you get to fight for the I-751 again. If you want to delay the deportation for some reason, you ask the judge at the Master Hearing for time to get an attorney. They will give you 3 to 6 months and you come back for another Master Hearing! Then the attorney will ask for time to file whatever relief is available, another 3 to 6 months or more for an Individual Hearing. If the case is lost, then guess what? APPEAL! That will take at least another 6 months to 2 years! And even after the appeal, if it is lost, quite often the Respondents move a few times and disappear so they don't actually get deported because ICE can no longer find them.
So it DOES take a very long time to get someone deported. I wasn't lying to you or sugarcoating anything.
In regards XXXXX XXXXX legal immigration system being broken, you are right about that, broken on both sides, as you can see.
As I said before, you are doing it the best way that you can. I know you want to save money on an attorney, but an attorney is an insurance policy. Often, nothing goes wrong, and you may feel cheated because you think to yourself, "Man, I could have done this myself! What did I pay this sap for?!" Well, this is the type of situation that an insurance policy like an attorney would have covered.
So give the CIS officer time to see if they can get that case reopened. If not, then you file a new I-751 and as the reason for the late filing, you show the evidence that you filed on time but CIS screwed up. If, on the improbable chance that they begin removal proceedings before you file a new I-751, no worries, you then just file it before the judge. And I've seen plenty of judges slam the government attorneys for CIS screw-ups because it wastes their time as well as yours.
