Hello from NY to All !!

How much do we need to get married??

Thank you in advance for your prompt response.

This says you will support, financially, the immigrant you are bringing into the US for 10 years (if I remember correctly) even if you divorce. I think I remember that you needed a permanent job that paid a minimum amount of $20,000 a year (not sure of the amount) or you needed someone else who would guarantee this amount.
It was awhile since I did this paperwork, but remember most of it.

Fiance & Marriage Visas: A Couple's Guide to U.S. Immigration

explains it all quite well under the 2009 system, including a chart of figures at the end. It won't be exactly the same but at least an idea

You need 125% of the poverty guideline if I understand this correctly, so if there are only 2 of you in the house it is an income between $18,212 and $22,760 depending what state you live in. I imagine you also need a few hundred $ to file all the paperwork, possibly a couple thousand for all the legal costs involved with it.

I am not a US citizen, nor have I been through this, this is just what I found on the above website , so I don't know if I got it right so don't do anything rash just on this advice :cool:

It cost me about $3000 total with medical check. After 2 years you need to do an Adjustment form which is about another $1000.
