My sister got her B2 US visa denied - What to do to make sure she gets it next time?

[Nodame]

My sister had her appointment at the US Embassy in Rwanda and was denied a B2 visitor visa to attend my wedding. I am getting married to a US citizen end of April this year, and I have been living in the US for 12+ years. I am a US Permanent Resident, I am well educated (in the US), have a good job, and enough savings to be able to support my whole family if they come visit.

My sister is a medical Doctor with 15+ years experience and is the head of a Hospital department, she is married, and has 2 children. She owns her own house and has enough money in her bank account to support herself as well.

I invited her to my wedding and I was planning to have her as my maid of honor. She applied for a visa, just for herself, because she wanted her husband to stay home with the kids. She had her employment letter and she had copies of my Green card with her, she even had both our birth certificates to prove that we are sisters. I gave her a letter of invitation, my bank statements, she even took her own bank statements, and the title and pictures of her house and family - In summary, she had all kinds of supporting documents that proves that she will be well taken care of, and that she definitely is planning on going back to her country and her family after my wedding.

During her interview, they did not even look at any of the documents she brought. They only asked her three questions:

- Who do you want to go visit?
Sister answer: My sister

- When was she born?
Sister answer: my birthday

- What is your relationship?
Sister answer: We are sisters

- Sorry, today you have been denied the B2 Visitor Visa. Here is a letter slip with reasons why you were denied.

That was it! They did not look at any paperwork she brought and did not even ask her any other relevant question - not even the reason why she is applying.

That letter slip was just a generic letter that says that not enough documentation was provided. But how can they say she failed to provide enough documentation when they did not even look at any document she brought with her?

She is my only sister, and I really wanted her at my wedding as my maid of honor, I don't have any other family member who would be attending my wedding.

We would like her to apply a second time, but we want to ensure that this time around she has a better chance of getting her visa accepted.
- I am thinking about personally writing a letter to the US Embassy in my country and explain her case
- Another option (costly) would be for me to fly to my country, and accompany her to her Visa interview and show my original documents (ID and Green Card) and try to explain to the visa officer in person why it would be important for me to have her present on my wedding day.

Do you think any of the two options above would help? What else do you think we could do? I am at a loss here, and any help on this matter would be very appreciated.

Hi,
Sorry for delay response. But my Answer might be helpful to others who overcome this kind of scenario.
You can write the letter to Embassy. But it must be a invitation letter. As you well know, B visa is purely depend on Interview. Documents are absolutely secondary.
The another option that you mentioned is surely not possible. You can not accompany with your sister at the time of Interview. Those who are applying for visa and scheduled for Interview only can enter to the embassy/ consulate.
Do you think any of the two options above would help?
Answer: As I mentioned above, You can write Invitation letter. But, second option is not at all possible.
What else do you think we could do?
Answer: She can apply for another time. At first time, Officer may think about home country tie up issue or length of stay in the USA. But, you can reapply any time later. Hope, you would have done another round of interview.
Kindly share, if any experience, she got.
Thanks

your letter won't be read because it has no LEGAL value whatsoever. You cannot accompany her to her next interview....interviews are private affairs, and the CO interviews the applicant, not their relatives or friends. She was not asked merely 2 questions...that nonsensical assertion is typical when someone gets denied and the rewrite history.
