I don’t agree this is necessary, especially as if it takes a year between application and interview like it did for me then you just need to re-compile all that evidence anyway.  I mean, feel free to o more work if you want but myself, my husband and my one kid who turned 18 all submitted the bare minimum asked with the application and all got approved on the day of interview. Made same suggestion to 2 couple I know and all 4 of the people also got approved on the day. 
 
i would be very surprised if they look at any of the stuff before the interview.

For the actual application, yes that’s all you need. I also had to submit marriage certificate and kids birth certificates, but if you’re single/not a parent you don’t need those.
You’ll want to take the tax transcripts to the interview. They may or may not look at them. They looked at mine, but not my husbands and not most people I know who did n400.

You need one more certificate, the marriage certificate between the parent and stepparent. It’s hardly onerous.

You need to prove your relationship. Proving mother <--> son relationship may be easier than stepfather <--> step son relationship.

As empathetic and sympathetic as I am to your niece's situation, I am still trying to wrap my head around why both of her parents up and moved to the U.S if they are so concerned for her welfare. And even more confused as to why at least one of them hasn't applied for a re-entry permit and gone back to live with her while she waits for her priority date to become current. She still has many years to wait before her PD is current. I guess it's the parent in me wondering how or why a parent would choose to up and leave a disabled child. Sorry if I sound harsh but I could or would never leave my disabled child behind. I have an adult son with autism and I would never even think to do such a thing.

Re-reading this thread, I think some of us are trying to answer the question “how can at least one of the parents be with the child to take care of them and not lose any more precious time with them” (per the post about how children are best gifts etc) when all OP actually wants to know is “what is the fastest we can get this child to the US because no-one is prepared to stick around and be with her if they can get a green card”.  

Why on EARTH would you cancel an approved immigrant petition in the (probably futile) hope she can get a B visa? All her real ties seem to be in the US, as others have said, she is very unlikely to get a B. I suggest one of the parents gets a re-entry permit and goes home to take care of their dependent daughter until she can move permanently to the US.

It’s confusing to me why her parents would have chose to leave her in the first place given how you have described the situation. Surely at least one can stay with her till she gets her visa?
 
 

Then you’re fine to enter the lottery. I think it closes soon, don’t wait till the last day. 

and please, don’t let her do this again. If her flight was delayed and she did leave the next day - despite it being out of her hands it is a verified overstay in that situation. She should always plan to leave at least a couple of days before her i94 expires, because stuff happens…weather, technical problems, etc.
 
 

In the heading of the thread.

It’s a parental relationship, the evidence is the birth certificate. 

I presume you mean your husband was on a tourist visa, not the stepson.
 
safest route is for you to file ir2 petition- your husband can file for F2A son of LPR but those petitions have lower priority and there is a risk that the priroty dates retrogress at some stage which will make it even longer. If you do it this way, probably 10-12 months uscis processing times (this shows at most uscis service centers but one is 16 months), 2-3 months NVC processing time, plus however long it takes to get in the interview queue at CDJ. Unlikely to be looking at less than 2 years till he gets a visa.

You cannot sign him up until he is in the country as an LPR. But you should be  able to get an ACA navigator.. go through your state health marketplace .. to give you a hypothetical estimate of what policies would cost if he was signing up now 

and please, don’t let her do this again. If her flight was delayed and she did leave the next day - despite it being out of her hands it is a verified overstay in that situation. She should always plan to leave at least a couple of days before her i94 expires, because stuff happens…weather, technical problems, etc.

Yes 
a parent visa is an immigrant visa
all immigrant visas have the same document requirement at the embassy regarding the “civil documents” page. That includes a police certificate. Make sure to follow the link to “reciprocity tables” to see exactly what is required for your country.
the only difference in documents are those proving the parent-child relationship as a basis for the i130

Some things are needed to file for the petition and others for the visa interview.  It is all explained in the DoS pages as well as the instructions for i130

please read them both properly.

What am I missing here? If they’re meeting in Turkey anyway why not have a proper in-person marriage there rather than a zoom wedding?

Communicable diseases and a couple of other issues are inadmissibilities and so the focus of the exams , but it’s by far not the only thing they discuss.  Lung cancer would be obvious anyway because the medical requires chest x-rays.

The visa medical examination requires
a medical history, obtained by the panel physician or a member of the physician’s professional staff, from the applicant (preferably) or a family member, which includes: a review of all hospitalizations a review of all institutionalizations for chronic conditions (physical or mental) a review of all illnesses or disabilities resulting in a substantial departure from a normal state of well-being or level of functioning specific questions about psychoactive drug and alcohol use, history of harmful behavior, and history of psychiatric illness not documented in the medical records reviewed; and a review of chest radiographs and treatment records if the alien has a history suggestive of tuberculosis a review of any other records that are available to the physician (e.g., police, military, school, or employment) and that may help to determine a history of harmful behavior related to a physical or mental disorder, as well as whether illnesses or disabilities are present that result in a substantial departure from a normal state of well-being or level of functioning. a review of systems sufficient to assist in determining the presence and the severity of Class A or Class B conditions. The physician should ask specifically about symptoms that suggest cardiovascular, pulmonary, musculoskeletal, and neuropsychiatric disorders. Symptoms suggestive of infection with any of the excludable communicable diseases (tuberculosis, syphilis, gonorrhea, and Hansen’s disease) should also be sought. a physical examination, including an evaluation of mental status, sufficient to permit a determination of the presence and the severity of Class A and Class B conditions. The physical examination is to include: a mental status examination that includes, at a minimum, assessment of intelligence, thought, cognition (comprehension), judgment, affect (and mood), and behavior a physical examination that includes, at a minimum, examination of the eyes, ears, nose and throat, extremities, heart, lungs, abdomen, lymph nodes, and skin all diagnostic tests required to identify communicable diseases of public health significance, as well as other tests identified as necessary to confirm a suspected diagnosis of any other Class A or Class B condition.

and please, don’t let her do this again. If her flight was delayed and she did leave the next day - despite it being out of her hands it is a verified overstay in that situation.

I (U.S. citizen) married my Turkish husband in Turkey. The process is very easy for Americans to get married there (I'm not sure about Iranians). All you need is an affidavit of eligibility to marry from one of the consulates (the consulate depends on where in Turkey you decide to marry), translated birth certificate and passport, and passport photos. I have read that if two non-Turkish people get married in Turkey, they will need to submit some sort of letter from wherever they are staying basically stating that they are, indeed, staying there for a short period of time.  As others stated, you will need to have at least two witnesses at the ceremony, and it will be much easier for you if they speak Turkish, as you will need to demonstrate that you can understand what the marriage officer is saying to you. There are loads of beautiful places to get married in Turkey!

There are no derivatives  allowed on immediate relative petitions (parents are IR5). There is no way they can all come together.  Fastest /cheapest way without leaving little kid alone is for one the parents to get a green card then that parent sponsors spouse + minor children as derivatives.  However there is a high chance of the older sibling aging out if they are already 19 - they can still be sponsored by the parent as long as they remain unmarried, but will take longer.

There’s no problem with the background. But why ask after you’ve submitted when there’s nothing you can do about it anyway?
 
please don’t post identifiable photos of yourselves all over the internet, sheesh.
