I am on a B1/B2 visa and want to open a Boeing Employee Credit Union (BECU) checking/savings account in Washington State. My purpose is so that I could have a checking/savings account with 0 USD maintaining balance that I could use to save some money and then spend for travel and leisure and treating relatives, whenever I visit my relatives who are US citizens in WA. I have family members who have accounts, which makes me eligible. The only thing that I’m lacking is an SSN (which I am not qualified for because I am not a US citizen or worker), or an ITIN.
Can I apply for ITIN to do this? Is this a bad idea? I wanted to specifically ask if having a US bank account and an ITIN will have any future ramifications to my plans of applying for H1B, or like when my current company would sponsor me for an L1B visa, or if in the future I would decide to take a masters degree in the US via F1 visa, or if in the future there would be opportunities to apply for a green card via employment based immigration. Will this pose unnecessary risk and questions?
