My US B1 Visa experience Chennai India

[APPROVED] B1 Chennai — 23 Sept 2026 — M33, Married, no prior visas, no refusals, no travel history

I submitted DS-160 on 7th april, searched slots for 10 days and booked biometric at Hyderabad for 16th July and interview at Chennai on 23rd Sept.

Interview appointment
Reached a day earlier to Chennai from Pune, Stayed at Ibis City Centre, 800m away, they had a complimentary drop off. Appointment was 8:30, left at 8:00, was in line by 8:10. Security, fingerprints, then at interview window in about 10 minutes. Two ahead of me, both approved. Officer was a lady in her 40s.

VO: Hi
Me: Good morning.
VO: Passport, please.
Me: Here is my passport.
VO: What's the purpose of your travel?
Me: I'm going for business meetings with my US engineering team. Talked about review and product roadmap for xyz project
VO: What's your role in your company?
Me: I work as a technical lead for xyz
VO: Oh, so you work on the xyz?
Me: Yes.
VO: What are these meetings about?
Me: Over the two weeks, talked about the project activities in 2 lines.
VO: Who will sponsor this trip?
Me: My employer, xxxx, will be sponsoring this trip.
VO: Does your family travelling with you?
Me: No, it just me.
VO: (Standard security questions)
Me: (Answered no to each)
VO: Your visa is approved. You will get your passport in a week. Safe travels.
Me: Thank you!

no documents were asked, I feel setting the clear context for visit worked for me, also the Visa Officer was seemingly interactive.
I was over prepared but I saw people with clear intent had better chances of approval.
I saw the guy before me answering purpose of travel with one word “business” and then answering in yes and no’s however when asked about why he need to go he mentioned very clearly, he was asked for invitation documents, salary etc but ultimately approved. I wouldn’t advise following that but simple and clear purpose do help.

LCD Landscape to portrait rotation at runtime

My project requires to display screen in portrait mode, the lcd is native landscape and cannot be configured via SPI command to modify MADCTL register to change orientation.

I am using 800\*480 RGB565 display from LXD with sitronix display IC ST7262, my MCU is STM32U5A9 and using LVGL for UI.

Now, I need to rotate the framebuffer by 90 every display flush. I am using lvgls software rotation and have the nemagfx wired in my lvgl code, so I was expecting lvgl to pass on the rotation as well to nemagfx which is not true, ultimately i see delays in animation or screen change, there are no pixel glitches or screen tearing it just don’t feel smooth transitions.

I also have double buffering enabled, I render partially to save up on cpu cost for composing full disp.

I don’t know how common it is to use the native landscape lcd in portrait mode but I am struggling to get a smooth lcd performance here.

The claude says lvgl sw rotations shouldn’t take more than 130 ms but does anyone have any experience and thoughts that how common this setup is and does it feel like workable solution i.e smooth performance while doing the sw rotates
