You can continue waiting or you can follow up by yourself or you can retain an attorney who can follow up on your behalf. Most likely - just more waiting since the backlog has been enormous in asylum offices.
This is not legal advice and a client attorney relationship is not created.
Keep waiting - there is a huge backlog in NJ. If you received a NOID, it's not the best sign that your case will be approved - I beleive there is only a 19% approval rate out of the Lyndhurst Office to begin with. You might want to consider consulting with an attorney at this point.
This response is not a substitute for specific legal advice and it should not be construed to create an attorney-client relationship.
Has something happened to make you more afraid to return to your country since you submitted the evidence in response to the NOID? If your situation has changed since last February in some way that has increased your fears you should ask the Asylum Office for permission to submit additional evidence of the change in circumstances, and explain how it makes you more afraid to return. If not, you may have no other choice than to wait.
