Green card received - when is the earliest I can switch to a different company

[jpotman]

I received my employment-based green card recently (June 2021). I am trying to understand when is the earliest I can switch to a different company in a similar role.

To go into detail about my case: I have been working for a US head-quartered company for about 15 years - it has been and remains a great place to work and I enjoy every bit of it - especially the contribution I make, the people I work with and the mission of the company. I started in the European offices and was transferred to the US on an L1A visa (I'm a British citizen, Indian by birth) about 4 years ago. Company filed for I-140 in Dec 2017, which was approved in 2018 and priority date became for EB1 India current in Aug last year and they filed I-485 for me in Sep 2020 and that was approved in Jun 2020 and received green card also soon after in June 2020. With all the investment they have done in me and the contribution I have made to the org, I feel like I want to increase my impact by opting to a different domain - there are several companies offering me similar roles at much bigger scope to make an impact and I want to change roles. Can I change companies without impacting naturalization in 5 years time? I read in a few immigration lawyer blogs that I should wait 6 months before moving. Given that I have been with my current company fifteen years (four in US) and that I am only now actively looking for a new role will it be viewed negatively by USCIS at naturalization stage. Any and all help and guidance will be highly appreciated.

A green card gives you unrestricted work authorization and you can start a new job right now. However, since your green card was employer sponsored (future employee for a permanent position), it would be wise to wait at least 6-12 months. This will help prove that the beneficiary (you) had the intent to work for the sponsoring employer.
