I worked in US with H1B Visa , for some reasons i had to convert my Visa to H4 for 1 year . Now i would like to start working again , So here are my questions . 1 ) Can i convert my Old H1B with my same employer from H4 . ( H4 to H1 ) ? 2 ) If yes , The USCIS fee would be equivalent to the new H1 or a smaller fee as i am not under the quota since i am applying COS to my old H1B ? Please provide your valuable suggestion .
