1. Maybe the I 130 was approved though I do not have any notice to prove that. In the words of the CO that went something like " I have done the hard part for you which is to establish that your marriage relationship is bonafide, now all you have to do is go back to the US and send me evidence that you are taking steps to re-establish domicile......"
2. Yes, as I am staying in separate quarters of the home of my family friends, they would be happy to give me a letter offering accommodations and I could give my statement of intent too, however, will the CO believe these statements. That's why I consider this determination to be highly discretionary and arbitrary.
I already have plenty of funds in US accounts. I tried to tell the CO back in 2009 that I am not a w2 slave but being a democratic administration back then, as it is now, they don't take kindly to people who can live entirely on passive income and who fail to do their patriotic duty of being a w2 slave.
4. If I file a I 130 with a TX address, is it a given that it will end up at texas service center?
