Hello and thank you for the opportunity to assist you. There might be a slight delay between your follow ups and my replies as I am typing out my answer, or taking a quick break. Please remember that this is general information only, not legal advice, and no attorney-client relationship is formed.

I am sorry for your situation, but do not be too worried. Surely they will match the matter by your Alien Number and other data, and will see the mistake. Normally, one would send a certified letter to the same address where you sent the EAD and simply explain that this is what happened. Believe me, USICS gets these mistakes all the time.

Some may wish to wait until they get a I-797 NOA to say that USCIS has received your application, so as to reference that as well to ensure that the letter finds its way to the proper application, and some simply send it now. It really is your decision. Either way, follow up with a phone call 3 weeks later.

In your certified letter, explain what you send, when you send it, the mistake, and the correct order. Include all personal information such as the A number and a copy of your documents so they can match your letter to the application.

I hope this finds you well. Please remember that I do not get credit for my time with you unless the answer is rated/concluded by you (a bonus is not mandatory but is much appreciated); I work very hard to formulate an informative answer for you – please reciprocate my good faith. If you still need information, hit reply so we can chat until you are satisfied. You may always come back to it to ask follow ups on this topic free of charge.

Great.

Can I Send the
certified letter and also a new application(I-765) with the corrected information along with the Supporting documents which I have to send to them? When I call USICS after 3 weeks should I ask them to open a service request or taking a info pass to the local USICS office would be a better option?

Individuals in your situation may simply wish to send the supporting documents along with a cover letter that explains your mistake. Is it necessary to send a whole new I-765 just because the two blanks are switched but the rest of the petition is correct? Unlikely - they already have your petition.

When I call USICS after 3 weeks should I ask them to open a service request or taking a info pass to the local USICS office would be a better option?

No, just have the live person on the telephone confirm that your supporting documents have been received and that USCIS is aware of the little error as echoed in the cover letter.

Or you can make an Infopass appointment to do the same thing (you can do so online, you do not have to call them to do so).
