B-1 Visa

We live in Delaware. We had extended my parent's B2 Visa twice in the past. Once in 2016 and it was approved. Second time in 2018, but they went back to India before the decision on extension. For the second extension, we got a letter from USCIS stating, "Since they left the country, USCIS is not approving the extension, However they can travel again"

Again in 2019, they came and left the US in 6 months.

This year, they came last week on Jan 31 2022, but CBP in Philadelphia airport took them for inspection at the port of entry. After a long wait time, CBP came back and told them that they had overstayed and they had canceled their B2 Visa. CBP gave a letter that they can stay for three months and leave the country before April 30.

Though we followed the process defined, we are really not sure why they canceled the visa.

With this situation, Can you please advise what is our option,

1. Can we appeal for visa reinstatement?

2. Can we go back to the country and apply for a B2 Visa again in May ? Or should we wait for some time before applying again?

1. My Son was born in February 2020 in the USA, where my wife is on an F1 visa working on OPT. Due to the Covid19 pandemic, I couldn't meet my son for two years. Kindly suggest to me the way forward to meet my son and wife. I also tried to travel on a tourist visa and F1 Visa. Unfortunately, I got both rejections. I'm an Indian taxpayer and an IT employee. 

2. My brother is a US citizen, and he applied for our mother's green card. Everything is clear, all paperwork is done, but due to the pandemic, we are waiting for the interview date from March 2021. Do you have any information on how we get the date or how much time it will take?

3. My daughter is in Dallas, US, and under medical treatment. She is there with an IN40 visa. As a father, I want to be there during her medical urgency. How can I get a visa now to be with her in the US?

4. I am a US citizen currently in India. I am traveling back to the States in mid-February for two months and want to take my Indian-citizen senior citizen mother with me for that duration. Her last US tourist visa expired eight years ago. (She has an active Schengen visa on her passport) Is there a way she can get a short-term two-month visa to the US?

5. I stayed outside of the US for more than two years because of COVID-19. Am I eligible for naturalization? I came to the USA in August 2016.

What are the consequences if we extend parents visitor's visa's stay for more than 1 time? Will it be a problem when they come back to US again? Is the minimum time to come back again still 6 months?
