The I-555 is the Green card (same thing.  It is in plainly and unequivocally in all the instructions to provide a copy of the front and back of your GC.  Have you done that. How have you prepared your packet that they cannot find it?

Rachel you never sign anything without counsel.  The sheriff was probably related to your ex.

Rachel I do not understand at all your question.  Did you come on a K-1 visa?  Who are you marrying.  DETAILS.

Again agree with mind the gap.  Do not spend money in a lawyer that will surely rip you.  There are some decent lawyers, but most of them like to take advantage.  If everything fails, then go to a lawyer after asking for references.

Mind the gap surely has a point.  If you can prove spousal abuse, you enter into a completely different category with multiple protections and will surely win your case.

You are definitely in a difficult situation.  Your only way to win is to be able to proof that at no time there was an intention to deceive the government and that while it lasted, your marriage was a bona fide marriage.  The documentation you have will have some weight.  Can you prove commingling of funds and property?  This as you know is the most important thing.  USCIS knows that divorces can be very problematics and they know of some people being are  very vindictive so they surely will take this into account.

Nigeriaorbust is correct.  The i-755 passport stamp renders the proof as the lost GC.

Mindtherap has a point.  Maybe it is just a form letter.

Well if they ask , then comply.  I am surprised of their request because again I repeat that affidavits have a very low standing insofar as pertinent info.

It could be you do not even need the lost GC, like nigeriaorbust states.

Again, search and thou shall find.  It took me less that 15 seconds to go to the USCIS website and find all the pertinent info-----------form I-90.

Calm down.  There is a form to request a duplicate.  I do not remember the form number.  I do remember that the fee is around $100 dollars.  Again search the USCIS website and you will find the info.

I am having trouble understanding your question.  You say your husband´s car insurance and affidavits were not listed in the "document we submitted".  What document.  Nevertheless, let me say the affidavits are almost useless. You can get anybody to say you are an outstanding citizen even if you are a serial killer.  Insofar as you husband's car insurance, it does nothing to prove commingling of funds.  Therefore, concentrate and all documents that prove funds commingling and you will have no problem. (joint IRS transcripts, leases, health and life insurance, titles in both of your names including car insurance in both of your names utility bills (even if on only one of your names, it will show mutual address you can prove).

vamos i am glad you found the info about how to write a check, to whom you mail (Department of Homeland Security), tht you include in the memo Alien number and I-751, etc.   I hope your example helps others to really search this wonderful website and you can find almost all you need.  There is a wonderful section that step by step assist you in the best way to assemble your packet, with Acco fasteners, etc.

transcript

I do not quite understand.  If she refuses to divorce you, then do not mention it.   As long as she cooperates and attest to a bona fide marriage while it lasted, everything is OK.

Everything depends on your relationship with your future ex.  It would be better if he would actually back you up in a declaration that while you were married, it was a bona fide marriage.  Remember that what they are looking is for the initial impression of the marriage while it lasted, and that there was no intention to deceive.  Maybe he would cooperate.  Even then, if you can prove a bona fide marriage initially as well as commingling of funds, it should be approved.

The letter extends the expiration date for one year.  If still your permanent GC has not arrived, ask for a second extension.   Patience.  Some people have waited over 16 months.  It also depends on which center you have to submit.

It extends one year from the time the GC expired.

Agree with rshree.   Why you guys make everything so complicated.

Yes, if a section does not apply to you, enter N/A or none.  Again you should have info on the website on what to enter.  Please guys, read and research this website in all its multipole sections and you will find all the pertinent info.  Do not leave any empty spaces.

Only one check will suffice, but make sure to write in the right amount, and address it to the right agency.  There is a section on this website dedicated to the way to write a personal check, what you write in the memo, and under fees, you can check for the latest fees. Make absolutely sure you have all the correct info. Do not staple the check. 
Again, there is a info on how to complete your packet properly.  Please search and thou shall find.

When you lock it they ask either other info you submitted when you registered including secret questions, or they ask you to call and talk to them.  That way you should be able to unlock your account once they are convinced  your are the rightful owner of the account.

I would submit the documents with the CA address and then file a change of address.  Insofar as travel, I would advise to wait until you receive the appointment for the Biometrics.       Make sure to keep this appointment.  After that, then I guess is okay to travel for a short time.  Remember this is a priority so do not risk it.
