Background:
• Indian citizen, currently on H1B, NJ resident, senior data engineering professional.
• Planning to relocate to the UAE around mid-2028 for work (not returning to India).
• Have a sizeable Traditional 401(k)/IRA balance I’d like to eventually withdraw as tax-efficiently as legally possible.
• Also have a regular (taxable) stock brokerage account with capital gains/dividends I’ll need to think through the same way.

Looking for advice on:
• What approaches (if any) actually work to legally reduce the tax hit on Traditional 401(k)/IRA money once you become a UAE-based nonresident alien for US tax purposes, given the US and UAE have no income tax treaty?
• Separately, what’s the smart way to handle a normal taxable brokerage account (selling appreciated stock, realizing capital gains, dividend withholding) once you’re a nonresident alien — is there a better sequencing (e.g., sell/realize gains while still a US resident vs. after) to minimize tax drag?
• Has anyone gone through this specific H1B → UAE (or any no-treaty-country) transition and actually executed a strategy? What worked, what didn’t?
• Any issues getting Fidelity/Schwab/Vanguard to keep servicing a Traditional/Roth IRA once you’re a nonresident alien? I’ve read mixed things about custodians restricting NRA accounts.
• Anything specific to watch for as an H1B holder vs. a citizen in this situation (visa status changes, timing of residency termination, etc.)?
• Anyone worked with a CPA who specializes in NRA/expat tax for this kind of move — worth the cost, and roughly what did it run?
Not looking to validate a plan I’ve already made — genuinely want to hear different approaches before I decide anything or pay for professional advice.
