Immigrant Visa

I was on a H1B visa in US. I am native Irish. But my last country of stay was India. As we were in US we decided to do AOS. But after looking at numbers for October and November, decided to switch from AOS to CP.
KCC told I can goto Ireland or India. If I decide to goto India, I need to prove my residency there. So I decided to go to Dublin, Ireland for CP.
My interview was scheduled for 9th Feb. I got my medical done in Dublin on 6th Feb. I learnt later on that I could have completed my medical in US and that would have been okay. And would have saved the fees as I have insurance in US.

Anyways, reached to Embassy as scheduled on 9th and came to know that my interview was preponded by embassy ! They called my cell in US for the same before 2 days but as I was not in US, I did not check the voicemail and missed the date. But they were kind enogh to give me another appointment next day. They also told that technically I should have gone to India as my last stay before US was in India.

They asked for following docs.
1. Notification letter from KCC and Visa Appointment Letter from Embassy
2. Passport
3. 1 Photo
4. Medical
5. Fees (755.00 USD each in cash)
6. Proof that I qualify (12th, BS and MS all degree certificates)
7. Proof of valid status in US (All prior I 797)
8. Proof of Financial (Experience Letter from current employer, Summary letter of all my Bank accounts, Letter from Banks)
9. PCC
10. Full form Birth Certificate (should include complete name of parents)
11. Marriage Certificate

I also took following docs which were not presented.
1. Social Security Card
2. All W2s, 12 months Paystubs, 12 months Bank statements
3. Old Passports
4. Experience Letters from prior employers
5. Evaluation of MS in India as MS in US
6. Evidence of Relationship with Spouse (1. Photo album of wedding & togather in US 2. Lease agreement for apartment)
7. Birth certificate of my daughter who is born in US

I took 1 copy of all documents above, they asked for copy whenever they needed. First they asked for my docs and then for my spouse. So I had prepared 2 folders as below for me and 2 for spouse

1. Documents that they asked for in the appointment letter along with a copy 2. Extra supporting documents without any copies as they did not ask for them !

After waiting for 30 mins, I was called for interview.
I had to take oath, everything in the forms (DS 122 and DSP 230) is correct. I was fingerprinted.
And then I was asked following questions.
1. How long you lived in Ireland?
2. How long your parents lived in Ireland? Why & When did they move to India?
3. Where do you live in US?
4. Where do you work?
5. When did you apply for the DV lottery?
6. How many applications did you have for DV this year? 2(one for me as primary other for my spouse as primary)

My husband was asked following questions.
1. Where do you work?
2. How many employees are there in your company?
3. Why your employer, residence and job location are different? Answer - consulting in IT
Thats it. We were told to sign on back of 230 - Part 2. And got the stamped visa and yellow package for immigration officer in an hour.

At last, we were relived and came out of all tensions.

We had a return flight after 3 days. Surprisingly our Immigration check was done in Ireland before boarding the flight, by US Customs. Again, we had to do fingerprint and our passport was stamped. After reaching Newark, we did not have to go via Immigration check ! Directly went for customs !!

Interview Tip: Contact Embassy for whatever questions you have. On the board someone said chained folders, stapler, stroller... is not allowed. But with Irish Embassy we could have taken all of them. So it is better to contact them rather then relying only on message board !
I wish you all best of luck.
