Yes you will need the waiver if you apply again within 2 yrs of the previous approval date.
Anyone that says you do not is setting you up for failure. 
Because, If you submit the waiver and it is not needed, they will ignore it and process your case normally.
However, if you do not send it and it is is needed, you will have to start over and lose weeks and weeks of processing times.
 
You have done the right thing by submitting the withdrawal letter with an explanation.  If you reapply, you will need to provide the letter they send you notifying you that your old case is closed.

Most important is that you prove that you plan to return home after ur time is up and whatever you do, don't overstay.  That will severely impact ur future chances.

why do u care what happen to her in 2 years?  what difference to you after u divorce?  other already told u that her problem not ur.  worry about ur problem divorce.

So it takes a year to re apply again. And wow 6 months before they responce your email for withdrawal ..but i guess its better to wait the right time.. Thank you so much for giving me this concern responce.it really englighten me and helping me to pursue my dreams and not give up... Godbless you so much and your life and family.. I hope i can reach you again nexttime for some advice

Best choice would be NOT to use that visa unless it is for the purpose it was issued.  If you are found out, you could be sent back home and banned for years from reapplying.  A member of my family (USC) had his wife (UK) banned for 10yrs and all she did was overstay her old US visa in 2002.

You should take action yourself to notify the embassy that you don't intend to use the visa and the reason why because it WILL effect your next attempt if there is one.

Ask you ex to submit a withdrawal letter.  ONLY he can do that, you CANNOT.  It should expire and die on its own but it may not.  That is from my own K1 experience in 2016.  My fiancee had and ex.  They previously filed for K1 it was approved and they broke up before her interview.  15 months later we met and applied ourselves.  Prior to filing the embassy and USCIS both said that the old case would be no problem because it "should have" expired, so we filed in 2016.  At her 2016 interview she was refused due to multiple petitions for same beneficiary.  The old case was 21 months old at that time and they refused to acknowledge the expiration.  I had to locate and contact her ex here in the US and convince him to submit a withdrawal letter.  That cost us 6 months or waiting for the letter to take effect, allowing us to re-apply, and then 6 more months waiting for our 2017 case to process.  If there is any remnant of that old case that is not "officially" closed.  They will ambush you with it at the interview and wreck your next attempt.  They will allow you to reapply wait months and months, pay all the fees get all the way to the interview and THEN they will send you home with your passport.

If your goal is to meet a good person and make a new life in a new place, don't be discouraged by comments here or at home.  My fiancee is one of the most resilient ppl that I have ever known, because of that we have persevered and her visa was mailed to her 24hrs ago.  Be smart, be careful and be honest and you will make it.  Good luck.

It always amazes me when people who have the privilege of travelling on ESTA make stupid decisions (like overstaying) and lose that privilege, especially if they complain about how "unfair" it is later on when they realize that they will have a hard time getting back into the US again.

Yes, it had nothing to do with the ban since the ban has been over and done with for a few years. However, she has a history of overstaying so the IO was completely correct in denying her the visa. It's not a disgrace, it's the IO doing her job and keeping her eyes open to people who have broken the rules before as they could very well do it again.
 
Like others have said, there's not a whole lot you can do about it. She made her bed and now she has to lay in it. =/

The interview is not as tricky as it may seem.  Generally, they don't typically know more than what is presented in your documents.  Criminal history, public records information is part of the background check that they do indecently.
 
If the person answers questions or presents information that is not consistent with what was provided in the documents and background checks that is basically and automatic fail.  From what I have learned here, they seem to like to ambush you with information that they find that you have not come forward with.  The more they find the worse your chances become.  There is also no way to know how the person presented themselves or if they were clear and transparent at the interview without being there.
 
Having the lawyer do all of the work seems like a great idea, but I think it leaves the client knowing less.  We completed all of the documents on our own and worked side by side to make sure everything was correct and consistent on every document.  By the end we both wound up with crystal clear memories of what was presented vs what we had shared in conversations and chatting.  I think that it helped her to be supremely confident no matter what was asked.  That, plus the fact that our backgrounds were both very simple with no crimes or issues if any kind (only my divorce).
 
The only way to eliminate any fear or doubt is to first know everything you put on paper, and to put everything on paper so that you are answering questions that you already have answers to and not things that you thought they would not know or ask.
 
 

A K-1 sucks the joy out of wedding planning anyway given the fears of denial/RFEs and uncertain processing times. 

I always had a returning one but have never been asked at the point of entry to show one to the officer. You should be fine

Send everything you have and let them do their job... 

One way tickets are perfectly fine, so go ahead and book one.

I could be mistaken, but this sounds totally like you’re fishing for what to use to report someone to USCIS. For someone who’s “just curious” you’re asking a lot of detail on a fairly specific presumably hypothetical case.

That is true, USCIS does not enforce their own rule on the expiration date. Not for everyone, not for all countries, so back to
my question why the PI ? Many had 1 or more petitioners and are filing again without any problems even though it is the exact same situation,
where beneficiary did not go to the interview due to a failed relationship and the petitioner never bothered to withdraw / close the
petition. However, as soon as a K1 is refused and returned to USCIS you bet your bottom dollar that it is then allowed to expire
on purpose (due to an old law suit) and petitioner will receive a letter of expiration.
I am inclined to believe that only a law suit against these so called 'not withdrawn' petitions can make it possible to move forward
by forcing them to close out these old abandoned petitions.
Why should a beneficiary have to get 'stuck' in the process because a petitioner refuses to withdraw, makes no sense.

Why didn't you think about this before your fiancé spent all this time, money and energy to get you here? Contrary to popular belief, the streets are not paved in gold. Your fiancé paid a lot of money and spent a lot of time to bring you here. Additionally, he sacrificed a lot. I know I did. Just because this whole process for you was "Free" does not mean it was free for him.
