I immigrated to the USA 3.5 years ago and my children stayed with their father abroad, I was going to settle for a year and then we would look at visitation. Before I left, my ex typed and we signed a maintenance agreement which was never filed at court, but he understood that it would take 6 months for me to be able to work and was gracious in that regard. When I arrived here, and looked at the job market I realized I would not be able to afford to pay him what I said I would (he typed the agreement up and said I must pay what he had been paying, but he had a corporate job and I have never had one). I kept in contact with him regarding this. AS soon as I got my green card COVID hit, and everything shut down. I was unable to find work until July last year (2021) and I sent him 25% of my income. I worked from home tutoring kids as that is what I have always done.
I am currently studying and my ex has refused to accept any money from me unless it is the amount he wants ($800pm). I can't send that, so I have opted to pay money to the kids school directly, which I have done all of this year.
Recently he got an attorney and said I owe a ton of backpay for the last 3.5 years, at the rate of $800.
There is no court doc stating what I should pay. He will not write a letter saying I have paid. I have all my proof of payments.
What on earth do I do for my application??
