whats the resignation prcess at EY and things to consider for people who are switching to another company on H1B visa?
Make sure you take experience letters signed by your current manager/HR. You may need it if and when the new employer files for your new I140. Chasing old employers for those letters is no fun.
What should the experience letter contain?
There are no set templates for these letters. Just make sure your job duties are listed with the correct job title and dates of employment. If you held multiple titles then list them out separately. I like to have these letters in a format similar to a LinkedIn profile. They are usually addressed to "Whomsoever it may concern". Even after doing all this, the law firm at the new employer could easily ask for more details but usually those open ended letters do the trick.
New employer will file a petition, once the petition is approved you can notify current employer. 14 days notice period is between you and the employer, and how you work it out. After that you can start at your new job.
