US Immigration from Panama

hello

I recently received my EAD card, I read all the documents they sent me but I am a little confused.
Can I work with EAD card directly?

Don't I need something else to verify my status? For example.

I already have my EAD card, in two weeks I will receive my social security number, with that it is sufficient proof that I can work and how do I prove that my documents are in process?
I usually carry with me copies of the letters that USCIS sends me about my cases, my passport and my old social security number.

I also read that the employer must fill out Form I-9, there he is aware of my legal process and my status?
I looked for information on the USCIS website but I'm still not very clear.

The back of the card says "this card is not evidence of U.S. citizenship or permanent residence"
I understand that there but what can I use to prove that I can be in the USA while my papers are in process? the EAD card? USCIS letters?

Other than that, after getting my EAD, what's next?

If you need anything else so that you can help me, I will gladly let you know.
Thank you.

hello

I would like to know if I can appeal my adjustment of status case?
What happens is that I sent the document a week ago but to the wrong address and I have until the 21st of this month to send everything, I sent my documents to the Chicago lockbox and it was another address. I'm waiting for them to be returned (if they are returned)
It gives me the option of uploading it online but they ask me for the medical and vaccination form, which is only one and cannot be opened. I was thinking of uploading everything I have and explaining that I will send the papers by mail, I just need time to send the documents

thank you.

If you already have paid for the biometrics for your work authorization (already approved) do you need to send the fee again for the biometrics on the adjustment of status?

hi how are things?
I have a question about how to fill out the form with a second sponsor,
the uscis asked me for the 864 form again, I suppose my husband could not comply with what they requested so I got a second sponsor.
For that, then I fill out the normal form with the information of the second sponsor or is there something else? If you have any videos, I would also appreciate it.
thank you so much!

Hello how are you?
I would like you to help me.
I am very confused about something and I need to clarify doubts...
I recently applied to form I-765 application for employment authorization, a few weeks ago I received a letter from the uscis rejecting my payment and saying this:
"Recently, you submitted and application for immigration service. that form was submitted with an extra remittance that its not required to process your application" they returned the payment to me too.
then a week later I get another letter about the I-765 format, I will attach a photo of what it says since it is a lot of text for me to write.

So if I am eligible for the extension (from what I understand) how would I go about getting that extension? Do I have to fill out some form or something? Or do I just take that letter to an employer and can I work? I don't know how it really works.
my EAD expires on 07/24.
