Hi bro, i have updated my ds160 due to deferal of admission. So i need to give both ds160 confirmation or the latest one? Also do i need to inform them about please update my ds160 or only speak after they ask anything?
So if you have updated your ds160, your appointment confirmation has the new ds160 confirmation number, then you dont need to do anything else. Ypu may bring both the ds160 for the interview .. but if the new 160 number is updated everywhere it is fine.
@@pratikian in appointment confirmation ds 160 number is of old one. I have already took the appointment from the old ds 160 number. Since I have deferred the admission I have to do some minor changes in ds160

Hello thank you. Can you elaborate on where the locker facility is? Is it in the entry of the embassy? Can we also deposit our luggage?
It is near the US counsulate. I am no sure, but I dont think you can keep luggage there. Only small things like mobile and wallet only can be kept there. But I am not completely sure, you may cross check this with someone.
Do I need carry my photo with me for F1 biometric at Mumbai centre?
No they will click your photo during biometrics.
Great effort
Great work with the demonstration in Blender. Please continue creating more pedagogical examples like this.
Hi Pratik, my ds160 has my given name different due to typing error and I have my ofc appointments due in 3 days, is it possible to correct ds160 at the ofc center Mumbai ?
So it is possible ... they might take some charge for it. It was 500rs the last time I heard.
Is the interview held at Signia Pearl, G Block, BKC in Mumbai?
Thats right. Here is the complete address Signia Pearl, C49, G Block Rd, G Block BKC, Bandra Kurla Complex, Bandra East, Mumbai, Maharashtra 400051, India
@@pratikian thank you for the prompt response
Thanks bro very helpful
So, I have a question. If I have 3 mean images from realigned scans corresponding to 3 experimental conditions in an fMRI experiment, should I corregister the 3 of them to the anatomical image? Like, I have to make 3 seperate batches or put them to the 'other images' option?
3 seperate batches, as the coregisteration matrix for the 3 images would be different.

Hi , thanks for the video. Can you please tell me how much time does the entire OFC process take ? I mean your time was 1.30 ? When did you come out of consulate office ? I just want to plan my return travel back to my city so wanted to know
That depends on the number of people who have got the same slot. Mine took about half an hour. But i would recommend to keep enough time. Atleast 1 hour.

Great!!
Awesome. Really nice !

Do they correct document pickup location? if asked
So, i am acctually not sure about ... however if you want to change it because you got a different counsulate maybe the following reddit can help www.reddit.com/r/india/comments/14hmkvi/question_about_us_visa_passport_pickup/?onetap_auto=true&one_tap=true
Hi Pratik, Typically how much time the VAC process takes, assuming all documentation is clean? I got the same day appointment for VAC and Consular. VAC is at 8am and Consular at 10am. I just wanted to know from your experience if the 2 hours gap between VAC and consular is good enough assuming a smooth process at VAC.
So it acctually depends on how many people are there that have got the appointment at the same time. I would say the max time should be 1 hour. But if possible ... i would reccomend to not scchedule the biometric and interview at the same day... as sometimes you never know what may happen... so if possible ... i would reccomend to reschule such that the interview and biometric are on different days!
@@pratikian Thank you for the response. That's helpful. Unfortunately I have no rescheduling opportunity left so I have to go for it on the same day and try my luck. Let's see how it goes.
@@krishna1698 I see. Well in that case dont worry. I came out of the biometrics in 15 min. Shouldnt be a problem. By the way which visa are you applying for ?

Hey so M1 visa is a bit new to me ... based on the research that I have done I dont see a medical exam requirement for the student M1 visa .. here is the official website .. travel.state.gov/content/travel/en/us-visas/study/student-visa.html Here is an indetail video about the M1 visa th-cam.com/video/5Ja_fa9Ul2s/w-d-xo.htmlsi=79Xmx-IMqYx8qN6o I know that universities ask for the different medical examinations.

Should we carry the documents single side printed or double sided?
You will need all originals only, i guess only your i20 has to be printed, bothside printing is fine for that.
what if there are two regions that are satisfying the threshold value but they are not adjacent? shall we merge them ???? like in this image image.slidesharecdn.com/sohamsirppt-190512202452/75/region-splitting-and-merging-technique-for-image-segmentation-16-2048.jpg?cb=1665794934 we can see that the corner pixel is also merged
