It is not advisable to seek an H-1B transfer while an extension is pending. It would be best to seek premium processing of the extension before seeking a transfer. You should speak to the attorney who will be handling the transfer about how to best proceed. You can read more about H-1B visas at http://myattorneyusa.com/work-visas.
