General Nonimmigrant Visa

Can a person on H-1B or H-4 visa be on the Board committee (Vice President) for the US based non-profit religious organization without pay (volunteer) ? Would it create any issue on visa stamping or GC process?

My daughter was born in Canada and is on my H-1 visa as an H-4 dependent. She is currently studying 2nd year of her Bachelor's degree and will turn 21 in July/2024. I have a couple of questions, and they are
1. By what date/age she needs to change her status from H-4 to F-1?
2. Once on F-1 status, are there a minimum number of months/semesters/years she has to complete before being eligible for a CPT or OPT?
 

Can an H4 EAD holder start a business in any state, or do they have to be in the same state as the primary applicant's H-1B?

Another question is can a relative's LLC file for H-1B if they have a need and it aligns with my MS coursework?

I am an LLM student on H4 (no EAD). My college offers paid and unpaid supervised externships (optional classes) for 2/3 credits as part of our course. Can I participate and work in an unpaid supervised externship on H4 without EAD?

I am an international student currently of F-1 visa status and will be graduating in May-23. I have the below questions:

1. Can multiple companies / employers apply for H1-B on my behalf in this upcoming H1-B cap pool?

2. If yes, is there a possibility that the employers might get to know about this?

3. Should my name in the passport and birth certificate match exactly? My birth certificate has an abbreviation my last name but my passport has my complete last name.

I am on H-1B working in the IT industry. My wife has H4 EAD, and with the same status, she is working in the hospital as a Physical Therapist.

1. Can her employer file for GC while she is on H4 EAD status?

2. If she is eligible for NIW, could you please let me know if the PWD and PERM are both required if her employer file for GC?

3. Can she use my priority date to file an adjustment of status?
