Deductions & credits

Hello All, 

Thanks for all the articles and info.  I had to process lot of info. 

Following the advice given by Dave and publication link given by PK,  I am planning to go with resident alien since day of arrival in USA.   Anyways, it provides me choice if Dual-Citizen or US residency and later is beneficial to me.  

1. I am not planning to change whatever I submitted in India. Two CAs explicitly told me, US income for Feb, Mar 2022 is taxable in India. May be because I am a Citizen of India.  Similar to these Residency Starting and Ending Dates are not applicable to US citizens. SC below. 

2. As per article for residency starting date, I will be US resident alien from Feb 4th.  So, most of my other questions render invalid . So I am good to declare US salary income received since then. 
Once again thank you for all the info.  @pk , @DaveF1006 and spending  time in web/law searches. 


 
Thanks,
prs
