回复：谢谢。修正申请是不是只需提交新LCA就行了？

If your job title, responsibilities, etc. remain the same and just the employer location change, your employer may just need to get the new LCA after your pending H1 approval and send the LCA to USCIS, not need the H1 amendment. Contact your employer/lawyer for this issue and they should know how to do it.
