H1B, H4 Visa

Hello Gurus ,

Here is my situation as of now 

I have booked for H1 non cap stamping valid till Aug 2021 at Mumbai in April . My latest H1 petition was approved for 3 yrs with an amended LCA for 1 geographic location.

Place of empolyment 1 : Client 1 ( where i am presently working )
Additional worksites :
Place of employment 2 : Client 2  ( where we have an SOW until Feb 2020  - although I am not working there . This client is within 50 miles of metropolitan area)
Place of employment 3 : Own Company ( we do have internal projects within the product development division  but i am 100% billed on Client 1 - again within 5 miles of metropolitan area ) 

Looking at the recent experiences of people attending interviews , one thing is clear . The questions are pretty standard .

1. What company do you work for ?

2. What is your designation and salary ? 

3. What is your work location and job duties ?

4. Do you work for a Client ? 

If the answer for question 4 is  YES . Then comes the complication of providing client letter .

In my case ,the client is not willing to give any signed document confirming my presence here .  

Here is what I plan to do and want to get advice from the community if this is a risk worth taking because my perm is in process and I don't want to disturb my situation now .

For questions 4 ,  I plan to say YES  and say I primarily work as product manager with development responsibilites at Place of empoyment 3 and have short term client assignments and billable when needed .
Right now  , I work at my own company and might get some assignment with the two mentioned clients in the future . My own company can give me the project documentation I need .

Is this response acceptable ?  Can all the forum members review my thread and post their comments here . It will be of great help to me to decide if I can take the risk of going to India . 

Thanks and Regards.
