Even though you have not recieved your appointment letter.It may be a good idea to start getting your paperwork ready for your appointment. Previous posts on this forum have details on what information is included in the second package. The documents listed in the 2nd package are the same as the ones in the 1st.
They are:
_ birth certificate
_ marriage certificate ( and divorce if applicable )
_ death certificate ( if applicable, for spouse or children )
_ deportation papers if applicable
_ police certificate
_ court and prison records
_ proof of High School diploma ( and higher education if any )
_ Evidence of support :
* affidavit of support ( I134 ) ( by a USC or LPR )
* job offer in the US
* money or assets on your name
_ your passport
_ US-size photos
_ medical exam : the 2nd package will indicate the list of accredited physicians and medical forms required for the medical exam.
If you still have not recieved your appointment letter in the next few days, you could call KCC and ask them to remail it.
