even I was scared but my this problem was solved as my family is in USA and meanwhile they were in India when I applied for the evaluation..... and they took my documents along with them and they mailed to ECE.
do u have someone in USA who can help u....or u can do is visit this page and know the details....
https://www.ece.org/
do u have some trusted courier service in your country who can take responsibility of your courier and handle to the given address. if yes you can continue with this process. Sometimes if u will ask for transcripts or attestation or sealed envelopes, usually colleges or universities charge very high.... which in actual is useless....(as what happened with me).... then I just called the ECE and they said send ur original documents and nothing else.....
hope this helps.....
