今天收到RFE了，要我（主申请人）和LD提供G325A。我还需要下面的东西（请见英文部分）：
请问这部分该如何写：The letter must indicate whether the terms and conditions of the employment-based immigrant visa petition (or labor certification) continue to exist.
我递485时是大学里的postdoc，09年去了制药公司，还是做动物实验（研发方面的），不知会不会有问题。
再次感谢！
Please submit a currently dated letter or other evidence from your intended permanent employer that indicates your current position, if any, proffered position, the date you began employment and the proffered salary or wage. The letter must indicate whether the terms and conditions of the employment-based immigrant visa petition (or labor certification) continue to exist.
Important: if you have changed employers since filing your application for adjustment and wish to use the provisions of the American Competitiveness in the Twenty-First Century Act of 2000 (AC21), the letter shall be issued by the new intended permanent employer. This letter must specify the job title and duties of the proffered position, the minimum educational and/or training requirements, the date you actually began employment and the offered salary or wage. This letter must be issued by an appropriate authority within the organization who is authorized to make or confirm an offer of employment.
