This doesn’t work with iPads.I just tried it on my tablet. it states you need to use Adobe Acrobat for Mac or Windows.  You need to use a computer OR if you can only use your iPad use Adobe Fill &Sign. It is also an adobe product. 

Acrobat free works fine for most...
What's not working now?

Adobe Reader is free.

Most users are able to fill the forms without experiencing too many problems, so the hiccup is probably on the side of your computer/tablet.
 
You might want to reinstall the latest version of Adobe Reader, and make sure to open the forms in Adobe, not in your browser.

Downloading and Printing Immigration Forms We provide free fillable forms through our website in PDF format, which means you can type your answers directly on the form instead of printing a blank form and writing your answers by hand.
For the best results, we suggest you download the PDF to your computer and complete the form using the latest version of Adobe Acrobat Reader rather than completing the PDF through your web browser. You can download Adobe Acrobat Reader for free from the Adobe website.
 
Download Instructions

In Google Chrome or Firefox, click the Download icon (second from the right) in the ribbon at the top of the page or press Ctrl (or Command) and S on your keyboard. After saving the form to your computer, click on the form icon to reopen it in Adobe Acrobat Reader. The Chrome extension might be on if, when using Google Chrome, you see this error message: “An error occurred. An error was encountered while processing the file.

Warning: Many non-USCIS websites also offer immigration forms for downloading. These sites may also ask you to pay for immigration forms (which are available for free on our website) and may not have the correct form version. In some circumstances, your case may be delayed or rejected  if you use an outdated form. You can find the latest version any USCIS form on our Forms page. 

If all else fails, take a look at SmallPDF.com -- it's a great site for multiple purposes, and they have a free trial for 7 or 14 days.  I registered for a monthly subscription, and it's been worth every penny.  You can compress documents that are too large, convert from one document format to another, etc.
 
Disclaimer:  My only connection to that website is as a happy customer.

If your computer’s PDF app lets you add a text field anywhere as Mac Preview does, you can do anything you want.

Will be easier to use a computer than a tablet.  I strongly suggest you try to use a computer instead.  Public libraries are good resources, if you do not have your own at home. 

On Apple Macintosh computers, there is an app called preview which can edit PDF files.

Do not convert these to DOC files. If you look at the PDF you will see there is a barcode at the bottom. The barcode changes as you input data. 
Try again with Adobe Acrobat Reader. I have been able to complete the forms with no issue.
If you are having issues on your tablet use a computer. Many libraries allow you to borrow laptops and computers. 

Download most recent version of adobe reader. Install it. Download the pdf and open it in adobe reader.
Some of these forms are a bit messed up and won't let you fill out a given field, where you've got two options: pen it in, or break the security on it. Breaking security is a bit legally gray but you won't be using the form for anything it wasn't meant for so nobody would care.

try pdf filler they give you a free trial and they have all the forms

Outside link but I used it when I couldn't edit it on some form.

There are more out there that you can search from Google but you'll need to find the one you like.  If needed. This is the one I liked so far, didn't do any new recent searches for PDF edit file. I use the online version. I'm using Windows OS but I don't think the web browser version do much difference on other OS but other can chime in.

Adobe. 

Mac Preview

Make sure you 1.) use adobe 2.) use adobe that has been updated to latest version 

I went thru EXACTLY the same scenario. The ONLY way to trace your pending application, to know the exact reasons why it was sent to USCIS, and to get application to be moving is- get your congressperson to be involved. Within a week petitioner would know the answers to all this questions. When I (petitioner) approached my Congressperson’s officer and filed the inquiry status thru them, it took them only a week to find out where my case is sitting and why and then all of sudden it started working ….However, I totally agree with Crazy Cat that there must be some complications in your pending application which makes US Embassy to have sent it to USCIS. In my case there were many red-flags, and case sent back to USCIS to investigate those matters thru their field office’s fraud department. If you wanna avoid all this then you may choose to file CR-1 case but no guarantee it will not cause the same result. I had IR-1 case. I chose to deal with those issues than just moving on…..Besides, I couldn’t have filed any other case anyway because the case was for IR-1 visa. Again, there were many-many red-flags in my case.

Congrat….Very happy that you are thru with consulate part now….And its so true that for some its a breeze and for some its a mountain to cross…My ex wife was 30 yrs younger than mine but they never issued her visa, but in your case age never even came into conversation. Its all about an individual officer….But you are still not completely out of hook from all these immigration jargons…like you need to go thru AOS and then naturalization (if you choose to)…I am sure you must be happy with your love here in US…finally….

I contacted the CDC they sent me information stating the K1 is exempt from vaccines including Covid until adjustment of status in US.   I sent all of it along with Video to embassy.   They replied, thank you for the information but we are waiting on reply from department of state.

A bit of a nuanced question, technically, the K1 does not require any vaccines for the visa itself. Even in regard to COVID, apparently, the shot is no longer required for the exam (though I'm confused if it's required to 'travel' to the US; that would be the only one required, but the rules have been in flux).
 
However, the State Dept strongly suggests that, as you will undergo the same medical exam that an IR1/CR1 filer would (and will need to do them anyway for AOS), you vaccinate yourself ahead of time according to their standards. I believe either the CDC or State Department has a list, but I'm not sure if this is actually complete. I viewed a list a while ago that only had a fraction of the vaccines listed on my particular Embassy's instruction page. For example, Warsaw mentions a flu shot...?
 
I would recommend going to the US Embassy in India's website and seeing if they have a medical information PDF. On the last page of that should be a "vaccine information" document that lists it out in full. 

It cannot.
 
The intent to marry statements must accompany the petition.

As far as I am concerned then I believe that there is nothing wrong in your submission of all these documents. Its just officer didn’t have time to check those documents. As to why officer requested these documents when those were already uploaded in their system with NVC before then you have to know that consular officers do always ask documents  even though those were already previously submitted. Before when everything was thru mail, then we people used to say that documents do get lost/missing while transferring of files from one location to another, but now when almost everything is digital then we don’t know why they couldn’t find those documents…but truth is still remained the same is that consular officers always ask some documents even though those are already submitted…maybe files get corrupted or deleted (by mistake) or whatever. But we have no option just comply with what officers ask because they are ultimately have the last say on the case…the sole authority to decide someone’s fate….A bit patience and understanding are all needed at this point of time, I guess. Good luck… 

The house is in US. Just like my bank accounts...

OP-
 
My ex wife and I were asked to come for a second interview. We had many red-flags. Our case was for IR-1 visa, out of India. It was very shocking and surprising that local US consulate called me in US (and to my ex wife in India) and asked me to go all the way different side of globe in India to appear for the interview. Immigration laws don’t require petitioner or US citizen-spouse (me) to attend interview at abroad, but I was still asked. Further, the request for second interview came almost one and half year being on AP. We had stoke interview wherein my ex wife and I were separated, and asked at least 15 same questions to see the consistency...Out of those 15 questions some were-What kind of car I have in US, names of two witnesses who were at our court wedding, what I like about my ex and what I don’t like about her, What are her hobbies, and we were also asked our favorite sexual position while making love...Yes, they did ask from both of us...and the consular officer was young white woman...
