Ok as an former RF Engineer and Pilot I'll weigh in here in a greatly oversimplified way.  The real issue is the receivers in the planes don't have the correct rf filters built in.   They never did and the FAA thought it wouldn't be an issue.  The FAA doesn't understand cell system design and thought that the emissions only travel on a horizontal plane.  Unfortunately some RF energy goes "Up".  C-Band towers at the end of runways can cause issues with the receiver for the IFR approach.   2g, 3g, 4g, 5g and 6g are simply standards for the core (landside processing and network) and RAN (RF side).  To have faster "speed" you need larger contiguous RF blocks.  In 2g we had 1.2mhz channels so you would be lucky if a cell sector had 10 megabits per second. 3g it is common to have 5 and 10 mhz channels. In 4g we have some channels at 20mhz getting over 160 megabits per channel, or higher, is a reality. Opening up the C band allowed for even bigger channels along with faster modulation techniques.   You "could" build 4g gear in C Band.
 
So wireless is not completely wireless.   Just the "last mile" to you is.   Wireless mostly makes sense for a mobile user (talking the US Market not developing nations) The cost to operate a network to deliver a bit if data is much cheaper and more reliable over fiber.  It takes less power, is less subject to outage and is easier to secure.
 
Soup to nuts the FAA issue is one where they haven't (allowed avionics to) keep up with technology.  This has come up in the past and not with just the "wireless" industry.  It's a $5 part that cost thousands to install because, well it's government.  Another solution is already there in the GPS network by using 2 sources.

I find duct tape is extremely effective too.

They just apply for the Visas.  There is no invitation or support.  They will be approved or denied based on their ties to Nigeria and their non immigrant intent.

If you would review the guides you would see that financial (sponsorship) info isn't submitted until the consulate phase.

Mary finished her interview and naturalization tuesday the 30th in Phoenix.   Glad to be all done.

There are valid federal uses to obtain an ITIN.  Just because Illinois encourages undocumented workers to obtain a ITIN does not make it legal to be employed. Some states allow for the recreational and medical use of cannabis.  Cannabis is still illegal under federal law.  Make sure that at each step of your immigration journey you disclose that you were using an ITIN in lieu of an EAD for employment especially if naturalization is the desired path. 

Usually you just need to show that you have "legal" not "tourist" residency.  In out case it was having a Mexican green card.   Contact the NVC asap otherwise once it is at the old consulate then the new consulate has to request it from the old one.

You can file the N400 now.  There is no need to wait.

I am sure the OP meant she came in 2021.   Based on his previous posts he doesn't seem to have a good grasp on Immigration.  If she left June 2021 then she doesn't need the green card to return to the US as the stamp on her Visa is good as a "green card".   She needs to return prior to that one year or if she has the green card the one year to her departure.
 
Another good reason to fill out a timeline.

Grab a copy of the NOA from the I-485 and file the EAD and AP for free.   I help out at an immigration clinic and weekly there are at least two that come in with an "emergency travel need" or "got a great job offer" and need one of those.   Free Free Free - words you rarely hear in immigration.

Mary had her interview this morning in Phoenix.  It took about five minutes after waiting about an hour.  I was outside in the car and she called me crying; I thought some disaster happened.  Took about 45 minutes then she and 5 other were naturalized.   
 
We have a trip to London next week so the only Passport Offices with openings are Honolulu, San Juan and El Paso!  We will work on reacquiring her Filipino Citizenship when we return.
 
Thanks for all the support!

An approved I-130 petition doesn't expire.  That is USCIS.
 
Look at CEAC and make sure the petition is still at the consulate.   File and pay for an updated DS-260.  Then contact the consulate and schedule the interview.  Do the medical in time for the interview.   Make sure all of the support documents are on hand for the interview.  The petitioner should also send and updated I-864 to the beneficiary to take to the interview.

Petitioner can file an I-824 to get the petition back to the NVC.  A new DS260 will be required.

The child can petition them in 21 years!

We kept a spreadsheet of all of out addresses.   We used Mary's at every step of the process all the way through to citizenship.   We also used the list when apply for other visas such as Canada.
